Hi @Kriss1501
It is currently listed as a known issue in "21.7.2 release notes" for RX 500/ RX400 cards, I am experiencing this issue as well on my RX 480. For me it even happens simply by having a lot of tabs open in any browser.
Hopefully, AMD will have it fixed by the next driver release.
Using DDU to uninstall the drivers, and then do a clean install of AMD drivers has helped me slightly, but definitely does not resolve the issue.
Kind regards
