When I try to open the glass roof then on the left the rear portion lifts and tries to move backwards. But on the right the rear part lifts only a bit (half as high as the left side) and the roof seems stuck - can move anywhere, especially not backwards.
The roof might have been closed for years.
I applied LOTS of pressure (with my fingers while I operated the switch) to get it lift more and get it moving backwards - to no avail.
Is this a known problem? The car was all its life in California (now in the EU). Might have been closed for many years.
The roof will close by itself.

Personally, I would NEVER be forceful with a sliding panel issue. Why? What if it then jammed in the partially open position and doesn't close (?) Now you have a much worse problem.
The sliding panel, to my knowledge, has various sensors - have you used a code scanner to check for faults? There's also delicate wiring in there that is easily compromised.
I would try using a mirror and a camera to see what’s broke or jamming it . Maybe a vacuum or having a mechanic blow it with a nozzle on their high pressure compressor might help .
if your lucky it’s debris , if not lucky it it just stays closed ! I think a broken part could be too expensive to repair. Or maybe a code was thrown .
