update:
I deleted ALL files of UE4, moved all my project to another place, reinstalled fresh and clean version of UE4.21.2.
File->package project->windows->windows 64 - selected newly created folder.
Nothing. 1 second of thinking from ue4, beeping, and again, same “log”, same nothing in folder.
I will try one more time to change all settings one by one and look, maybe one of them will help.
