The map specified on the commandline could not be found

Hello,

Yesterday I tried to start a simple Server from the Winows commandline however the Server just works fine but no matter what I do it won’t load the specifed map.
This occurs even on a new project with the Starter Map.

If I press okay the Server loads the Default map otherwise it quit.

Project is freshly builded and cooked.

Any idea what’s causing it?

The same for Server travel:

Thanks in advance.

BR,
Fabian
