Microsoft Windows 10 KB5001330 causes frame rates to plummet, screen flickering and BSODs
It could also causes potentially loss of user files, DNS issues and boot-looping on rare systems.
For now it is best to uninstall KB5001330 for ver. 2004 and 20H1 builds and KB5001337 if you're running a build older than 2004.
Until Microsoft have a solution for this.
Remember to Pause Windows update for a while - before uninstall KB5001330.
Hopefully in a couple of Weeks Microsoft has a solution and then activate Windows update again.
