just spent 3 days re-installing win 10 & about 68 pc games after getting 100s of these warnings & multiple errors,it all began when i updated win 10 to 2004 on a new amd machine rather on my intel machine,wish i hadnt started with the amd ryzen5 build
FYI I still get these errors but now only one group of 6 errors after a restart. I am running 2004 and I experienced the same thing you are now but after more updates were deployed to help fix 2004 problems they began to disappear with the exception of the six I get now.
