Has anyone with the issue tried this update by chance (or made sure it's installed?)?

I had the freezing problem when I had moved forward from 2004 to 20H2 and then I rolled back to 2004 and the problem went away - I'm still on 2004 and I won't install a new version until 21H2 later this year, but I am continuing to monitor this thread as this is a very concerning problem. Hoping an actual solution is found at some point since some people who have now tried 21H1 are still having some issues as well.
EDIT - Also has anyone tried disabling "Hardware Accelerated GPU scheduling"? I saw one post on reddit where someone had mentioned that resolving system freezes for them. So just something to try. Since I am not currently having the issue with v2004 I can't test any of this stuff.
Honestly, i wont try nothing else anymore. Im just tired about this, so many hours focus on that problem.
Anyway, i had the same problem as 2004, 20h2 and 21h1, so i think atleast for me its something about 2004 update that it's not solved yet on the next updates. I don't know what to do right now cause windows 2004 and next's makes my shooter games more fluid about fps than the windows 10 1909, but can't have cause system crash so..
