Rider can't start Debug Session

I'm working on a MAUI UWP app. The app is working fine, but somehow I can't start a debug session for it.

If I start one, the app starts, the background Task "Initializing Debugger" runs and then suddenly stops. The app is still running but is "detached" from the IDE.

Debugger.backend.log:

I can debug other MAUI UWP apps without problems, also I can open exactly this solution in Visual Studio and there the debugger works fine, but I would prefer to keep working in Rider.

Anybody an idea, what could be wrong here?
