I recently bought a Minolta XG-7, however, after checking if everything was working (it was) suddenly the shutter stopped working...?

The film advance lever didn't seem to go all the way and after some fidgeting with the bottom screw i realized the shutter was stuck halfway across the frame, not allowing me to release it. Is there anyway to fix this? Do I need to recalibrate the gears underneath the camera? Thank you for your help in advance!!
Update: Update: After further inspecting and research, I have tried to adjust the winder and idle gears however this has not helped at all. Is this worth a trip to a repair shop or do I just give up?
