Updated to Windows 10, v2004 - Right clicking freezes window

As the title says, I just updated to win 10 ver 2004 (from 1909) and this problem renders my PC practically unusable.
When I right click on a folder or file, the respective window freezes (and no context menu appears). I can still open other programs but, from the moment this happens I cannot even left click on any file or program even in another window, without the window freezing. If I reboot, I can now left click, but at the moment I right click, the problem appears again.

These are the things I tried (following, among others, some answers I found in tenforums):
- running Dism.exe /Online /Cleanup-Image /Restorehealth
- running SFC /SCANNOW c:
- disabling all services: System Configuration -> Services -> disable all (having hiden all Microsoft services)
- disabling all startup items: Task Manager -> Startup -> [I disabled everything]
- disabling all non-Microsoft context menu items using ShellExView
I did all the above and rebooted but the problem remains

Only booting to safe mode seems to work....

Can anyone offer some insight?

hi! Any relation to what file or folder you're clicking on?- Like a system folder or on a specific drive?- did you try checking for any more updates in Windows Update, or are you on the latest version?

No, any file or folder (at least a few I have tried). Btw, right clicking on the desktop or an empty area of a window creates no problems.

Also, I have downloaded all available updates from Windows Update.

Huh, weird. Any pointers in the event viewer, or utilization spikes in the task manager under 'performance' from any applications or services when it happens?

Unfortunately no utilization spikes.

As for the event viewer, although I am not well versed in it, I see this often:
"The Windows Search service terminated unexpectedly. It has done this 13 time(s)." I had disabled previously windows indexing, but now that I tried, I could not reenable it. I dont know if this is related, though.

Drivers and Updates current ?

My system does the same after update until Synaptics Pointing Device Driver is installed.

Hmm, I don't know either unfortunately. I don't see how the Windows search is related to right clicking folders, but who knows with Windows these days. Mostly what I find by searching around are things you've already tried. Maybe this is obvious, but have you tried to wait a while after right clicking?

Yes, for a long time. Nothing changes
