Game crashed after Servertravel

Can anyone help me?

Game packed with shipping settings!

Since I made the new map in the game I get this error (LowLevelFatalError [File:Unknown] [Line: 1121] GameThread timed out waiting for RenderThread after 120.00 secs)
when I select the map in the menu and from the lobby with a servertravel to the new map.

In the editor I have no errors only after packing and only with this map the other maps run perfectly.

Who can help me pls?
