What is the reason and/or fix for UE5 (5.03 & 5.1) freezing my whole pc?

Same issue here. I had this for a few months and a factory reset didn’t fix it. I then upgrades to windows 11 to see if that would stop it. It did for a while but Its just come back again same as last time. I changed my TDR I think its called(gpu time out) because substance painter wanted me to. I think this may have triggered it. I will know if this is my cause onces I take the time to try because the freezes aren’t so frequent.
