What's your hardware? I have the same problem that seems to come and go between driver versions. I have a AMD RX 6600XT. I've tried aggressively underclocking it, like you thinking it's some kind of thermal protection, but the issue resurfaces. And the Windows Event Viewer isn't helpful for debugging it. :/ Dual booting into Ubuntu and running the same games through Proton has no issues.
