I have an RPi 4 on which I installed xrdp to connect to it via MS Remote Desktop. But after login with the pi's username and the password, the grey login window disappeares and leaves me with the blue-greenish background.
Before login:
After login:
There is no error message which might indicate what is wrong.
What can I do to fix this? Reinstalling xrdp didn't work. Still the same issue.
(If noone knows how to fix it: Is there an alternative to xrdp I can use, which works with MS remote desktop?)
Edit: I am using a Win 11 PC to connect and the RPi is running the latest x64 Raspbian "Bullseye"
