Server couldn`t start in 20w20a

After restarting the Server the following lines apear in the console :

• [92mStarting game server now...[0m

• Wed, 13 May 2020 20:10:44 +0200: Starting game server

After that the server has a complete shutdown.

Restarting the server does not affect this problem.
