Desktop/Start Menu not clickable - I have to open task manager to fix

OK
I have done all of that.

Its still causing the same problem.

(I have even done a full reset of Windows 10)

If you like you can repair install Windows 10 without losing anything other than all installed Windows Updates.

How to Do a Repair Install of Windows 10 with an In-place Upgrade

Perform the following steps:
1) type: win + x (simultaneous)
2) type: a
3) type: alt + x (simultaneously)
Most of the time this opens administrative command prompt.
If the settings were not modified it may open administrative powershell.

If it is administrative command prompt or if you can open administrative command prompt type or copy and paste:
1) sfc /scannow
2) dism /online /cleanup-image /restorehealth
3) chkdsk /scan
4) net user test /add
5) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread
6) shutdown /r
7) reboot and sign on with the new user named test.

Report into the thread whether the new user named test has a desktop without the problem that the current user is having.

If there are problems with both users then open administrative powershell and copy and paste:

Code:

Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “\appxmetadata\appxbundlemanifest.xml”)}

reboot and sign on with the new user test and report the findings into the thread.

I have seen an issue like this before, but the way it would happen, is that, on a boot, everything would work fine, but, as the computer set and idled for about 10 Minutes or so, nothing worked, such as start menu, couldn't close out windows, etc.

The cause is explorer.exe hangs, and stopping and restarting the program would temporarily fix the issue.

The problem ended up being that a RAM stick was failing. Did a memtest for 24 hours and one of the ram sticks reported errors after about 4 hours.

I replaced the RAM stick and the problem went away.

One year later the motherboard failed, so I had to build a new system.

You should download memtest and do a memory diagnostic, just to rule out any memory issues.

Both users have an issue
I am trying the last powershell thing.
