There are no log files in appdata/Local/UnrealEngine/4.25 (I only have a config folder here, but its empty), Engine/Saved/Logs (this folder doesnt even exist), nor in AppData/Local/Microsoft/Windows/WER/ReportQueue (again, this folder doesnt even exist).
I have left the UE4Editor.exe run overnight, nothing happened. I opened it again, nothing; they just sit there with 0 CPU usage, and 17,3mb RAM. It doesn’t matter if I run it as admin, or from the Epic launcher, it just won’t launch. If I click on it a 100 times it will be in the task manager 100 times, but none do anything.
The only other UE related exe I’m seeing running is UnrealCEFSubProcess.
I have two questions: does UE require virtualization enabled in BIOS? (i tried with on/off, nothing, so probably not) or coudl it be that I had a plugin installed for 4.23, and that is why newer versions wont run? (even though I reinstalled everything?)
