You’re the first one I saw to mention minimized UE. That’s exactly what’s happening. It works just fine while I’m on the editor, but when I switch to another app for a while and then switch back to Unreal I get this Memory Exhaustion problem and it asks to save a bunch of level versions when I close it. Only restarting the PC solves it till next time.
