Unreal Engine Editor 4.27.2 suddenly does not start any more. A couple of days ago everything worked.
Now when I click launch I see the running process but do not see any UI at all. If I click launch again, I see one more process, etc.
Already tried to run as an Administrator, complete reinstallation, rolled back last Windows update, disabled Antivirus, updated Nvidia drivers - nothing helps.
Also, I cannot find any logs. The folder “Saved” simply does not exist.
My laptop is:
Windows 10 21H2, 16GB RAM
GPU Nvidia Quadro T1000 with 4GB.
Everything worked perfectly until today
Is there a way to enable UE editor logging to understand the reason?
Any help greatly appreciated.
UPDATE:
Only was able to get some logs when tried manually launch C:\Program Files\Epic Games\UE_4.27\Engine\Binaries\Win32\UE4Game.exe:

When launch UEEditor from EpicGames launcher or via shortcut - nothing happens.
