Looking up on TIS it’s stating that you need to do a health check and see which codes you are getting, there are 2 that will cause the sunroof to stay stuck. The first code is B2341(sensor motor failure) Sensor (motor) failure (When the sliding roof ECU (sliding roof drive gear assembly) enters fail-safe mode due to a problem with the motor).

The second code is B2344 Position failure (When the sliding roof ECU (sliding roof drive gear assembly) enters fail-safe mode due to a problem with the gear position.

After figuring out which code you have, your TIS states you’re going to have to do multiple test on the Sun roof system and see which component went out. Hope this helped out a little.
