When game start, there apper white window with close-cross and no text (see picture). After I close this window, the game stuck on load screen (the red cube in right bottom corner rotates infinitely.

Also, when I look to task manager it seems that process "UnrealCEFSubProscess" is dead. When I kill this sub-process, the blank white window re-appear again.

The problem appeared after last update. I tried to repair the game, also uninstall and install it again and nothing helped.
