I had installed Cygwin with X server on a Windows 10 machine without problems. Now I have converted the same machine to Windows 11 but not I am not able to run X server anymore. I get no meaningful errors. I have tried also reinstalling Cygwin with the same result. Here is the output when running the simplest case:
