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)

Same here, Everything was running perfect and there was this alert that an update is available and that as MS will stop support to version 1909. So, I did It. and Then WHAM! ever since that happened, my PC boots up, works smoothly for a mind blowing less than 5 minutes and seems like I am stuck in a time loop. Every move takes longer and longer, and finally Hell Freezes Over! How is one supposed to trouble shoot when the troubleshooter does not detect anything and when the system is ON, I can't even get the start menu to show up let alone try cmd. Rolled Back the Update, reinstalled, tried repair, reinstalled again, clean install, even reformatted the SSD, SSD manager also checked out OK but nothing is working ever since the damn update. I'm 10 days behind the slowest member of my team. MICROSOFT Has to tackle this issue. I kep all my drivers updated.

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

It should not matter that it's 2 yrs old because if they did not think the computer could use it they would not have let you download it.
