Gmod Server Start Error ...

Hey Facepunch User! I hope someone can help me. When I start my Roleplay Server, the console is loading and all works but it stops here “Writing cfg/banned_user.cfg”. I think the banned_user.cfg isnt the Problem, i think its something before that…

Here is a screenshot of the console, I hope someone knows a solution for this problem:
