UE4 freezes my PC

Well it makes sense but still I cannot put a finger on why only UE4 editor? If it is really a thirdparty issue, then other applications or games should produce similar anomalies too, right? For me, everything seems functional, except UE4. And the weird thing is there was no driver update nor Windows update at all. I’ve never encountered any UE4 freeze or crash until now.

Yes, it was turned on. I disabled this option for now and let’s see what happens.

Thanks for the kind advice guys. I’ll check everything you mentioned and let’s keep fingers crossed. It’s quite annoying for sure and I hope it gets resolved soon.
