You have already discovered a workaround but failed to take advantage of it. See how I used this in the following post. Inconsistent Computer Visibility Across Win10 Network
Thanks. This is a helpful workaround, and I will use it. However, I'd like to fix the real problem of the one machine's invisibility. I use 4 computers, many with dual-boot, and different operating systems, and this workaround doesn't really scale well.
It's all the more vexxing since that machine had the OS fully reinstalled from scratch a few weeks ago, and already has the network messed up.
I'm stubborn and am trying to find the root cause. The machine in question normally boots from the internal NVMe drive. But it also has a SATA hotswap bay, from which I can boot, and I have a few spare SATA 120GB SSDs I can use to test with.
So, I took it upon myself to try to figure out what caused it today. I spent a couple hours. I used Acronis Nonstop Backup to backup the whole drive every 5 minutes, or manually. This is the recipe I followed :
Install Windows 21H2 from USB drive without network on SATA drive
Rename machine
Install Winaero from USB stick
Disable web search in Winaero
Enable autologon in Winaero
Run Netplwiz
Bring up Task Manager
Click “More details”
Remove Edge from Desktop and Taskbar
Reboot
Select volume 6 on boot
Pin Control Panel to taskbar
Install Acronis from USB stick
Enable TrueImage nonstop backup to local dynamic disk
Change regional settings / change data formats - set 24 hour time
Language / options : remove US / QWERTY keyboard
Winaero : disable Windows update
Winaero : turn off driver updates via Windows updates
Winaero : disable hibernation
Use SystemPropertiesAdvanced to select default boot menu
Use SystemPropertiesHardware to disable device driver download
Disable People / Task view / Show Cortana in task bar
Reboot
Force nonstop backup
Install AMD chipset drivers from USB stick
Reboot
Suspend/resume nonstop backup
Install nVidia drivers
Change center display to main display
Suspend/resume nonstop backup
Install Hauppauge HVR-1265 drivers
Reboot
Suspend/resume nonstop backup
Disable onedrive
Install Echo Audiofire drivers
Set Audiofire to 96 kHz in Echo panel
Reboot
Suspend/resume nonstop backup
Install Kensingtonworks from USB stick
Suspend/resume nonstop backup
Install Marvell / Aquantia 10Gbps NIC drivers from USB stick
Allow PC to be discoverable on network
Local machine is now showing in network folder
Suspend/resume nonstop backup
Reboot
Local machine is no longer showing in network folder !!!
The network got messed up very quickly, without running any Windows updates, which were disabled. I hadn't even gotten all the drivers installed for all my devices. The Asus USB Bluetooth dongle still didn't have drivers per device manager. Neither did the USB to RS232 Prolific device. Everything else connected had drivers.
I'm at a loss as to what step above actually caused things to be messed up, especially since the machine worked correctly right after installing the NIC drivers, and then stopped working immediately on reboot, without anything else having been done in between.
FYI, this is a pretty loaded machine. The motherboard is an Asus Prime Pro X570. CPU is AMD 5950X.
All the PCIe slots are full. There are a number of USB devices connected, with multiple hubs. My home network has over 70 devices on it. The other 3 PCs on the same network have no problem, though. 2 of them use the same Aquantia AQN-107 NIC.
When I say above I installed Windows 21H2 without network, I disabled the Intel NIC on the motherboard. Windows doesn't have drivers for the Aquantia NIC in the boot ISO. So, it literally had nowhere it could connect from and get network. I set it up with a local account. If Windows had recognized the NIC, I would just have booted with Ethernet cable unplugged to accomplish the same. The other 3 machines are all setup without Microsoft account also, and with 21H2.

So, I made a second attempt. Cleared the SATA drive with diskpart, and tried again. This time I installed the network right after the install, and added drivers one a a time.
Here is what I did. It helps to have 3 monitors and a KVM switch to write all this down while doing it.

So, as far as I can tell the problem is caused by the nVidia 499.76 drivers / installer. It could be present in other versions too, of course. It's possible there is some interaction between these drivers and something else in the software stack in my system. In any case, this is very strange. nVidia shouldn't be messing with any network settings on the machine, so this is definitely a bug.
The good news is that removing all the nVidia components in Control Panel fixed the problem. Then, installing the driver through Windows updates worked. Of course, all the other nVidia components are still missing, and the graphics driver is backlevel (472.12).

Sadly, the good news was short-lived. Shortly after downloading the nVidia driver from Windows update, Windows decided to install the nVidia control panel. I rebooted. The local host could no longer be found in the network folder at this point.
I went to Settings / Apps & features, and removed the nVidia control panel, then rebooted again.
Still no sign of the local machine in the network folder.
Went to device manager, rolled back the display driver to "Microsoft basic display adapter". Rebooted again. Still no sign of the local machine in the network folder.
At this point, I don't know what to do to bring it back to life, except restore the whole disk from the backup I had done before I first installed any nVidia driver.
Surely some nVidia and/or Microsoft engineers ought to look at what's going on here.

I also tried Display Driver Uninstaller on my temporary OS disk. That also didn't bring back the local machine in the network folder, unfortunately.
I booted my NVMe drive, I tried to uninstall all the nVidia drivers using Control panel at first, and then DDU. But neither resulted in the local machine appearing in the network folder again.
Finally, I restored the full SATA with Acronis from the backup I did before installing any nVidia stuff. I did have to mess with BCD using EasyBCD in order to be able to boot both the NVMe and SATA drives from the boot menu. Booting came back with the local machine showing up in the network folder.
I still don't know exactly what the nVidia drivers are messing up as fare as network settings go. That would probably require a registry diff tool. I'm going to try a few older versions of the nVidia drivers to see if it's recent regression. The oldest supported for my 3060Ti GPU is 457.11 . Looks like that won't install on Win10 21H2. The oldest nVidia driver I could install on 21H2 is version 462.65 . I used the studio driver. It also has the problem causing the local machine to disappear from the network folder. Edit : I installed 462.65 again after trying a few other versions, and now my local host is showing in the network folder after the first reboot. On second reboot immediately after that, it's gone again. Sigh. I don't know what these nVidia drivers are doing, but it sure is weird. And they really have no business messing with the network...
Edit again: at the 3rd, 4th and 5th reboot, machine is visible locally again in the network folder.
Other systems on the LAN also see it. Really extremely strange.

I ran it locally on my Windows machine that can't see itself with the nVidia driver installed. It didn't have any effect, unfortunately.

Dear madbrain,
see my soultion here:
Win10 computer unable to see Win 7 PC /fileshares on network
It is crude, but it worked. It does assume that you have fixed IP addresses on your computers in the network.

When you ran the scanner on ALL PC's could it see them all and who is master browser it tells you and it stores who is on the network and windows doesn't search it asks mb
