Random Freeze and Unresponsiveness [Windows 10 20H2]

I updated from 1909 to 20H2 in an attempt to resolve issues I've been having pertaining to WMR (Windows Mixed Reality) and the HP Reverb G2 and now after a few days of having updated this issue has cropped up, as described by others: 

1. Pressing Win Key does nothing
2. Clicking on Start Menu icon does nothing
3. Right clicking on desktop does nothing
4. Ctrl+Shift+Esc does not bring up Task Manager

You can move your mouse, but you can't click on anything and the only solution is to press Ctrl+Alt+Delete and sign out and then back in again OR you can hard reset your PC. 

Restarting the PC doesn't fix anything. 

I've also tried sfc / scannow and Dism / Online / Cleanup-image / RestoreHealth and although sfc / scannow found an integrity violation and fixed it this did not resolve this problem. 

Another unrelated issue is that I had to reinstall my sound driver for my sound card, Asus Xonar DX. 

I suppose I'm rolling back to 20H2, good thing I made an image of 1909, 20H2 is NOT ready for prime time. Please fix your garbage operating system. If it weren't for PC gaming I would've gone Linux LONG ago. 

This is absolutely unacceptable, also WMR is trash to top it off. I suppose you will just roll over and die and let Facebook have a monopoly with Oculus. 

Pathetic. 

Issues with WMR: 

Perceived hardware failure was actually a WMR + Windows issue that could only be resolved via reinstalling / restoring the OS. I wonder how many cases of perceived hardware failure are actually WMR + Windows related. : WindowsMR (reddit.com)

Really annoying issue where after a WMR session there is like 3 second input latency induced into keyboard input. : HPReverb (reddit.com)

It isn't new. It's HP cb045wm. Over two years old now.

I formatted my computer. I'm now on Windows 10 1909. The random black screen or issue still remain. I'm tired of all this. I'm starting to look at any possible hardware failures. 

bro, is your pc "new"?  please share your pc specs.

It could be a hardware issue for you but as for me, I've reinstalled windows 5-6 times now. Reinstalled fresh windows twice. Sent it to GeekSquad 3 times and they couldn't find anything wrong with my hardware. Rolling back to version 1909 will not work for me because that's when I started to have the random freezing and black screen issue. I tried to roll back to version 1809 but it won't let me. Version 1809 was the only stable version for me. Anything after that is not stable at all.

My work laptop, a HP Zbook 15 G2, has just gone through the latest Windows update to 20H2.  Within a couple of hours of using it the laptop froze.  It has NEVER done this before.

There was nothing I could do except press and hold the power button to turn it off.

That was last night and I decided to call it a day as it was late.  This morning I thought I should make sure the laptop would power up, which it did without a problem, however within 15 minutes it had completely frozen again.  All I was doing was using Google Chrome!

If this continues, and given it has happened twice in a very short space of time I suspect it will, then the laptop will be unusable.  As an IT contractor without the laptop I cannot work and therefore cannot earn money.

MICROSOFT.  GET OFF YOUR BACKSIDES AND GET THIS ISSUE RESOLVED!
