Door locking driver side

Hello together, somehow my V50 just seems to develop a few quirks… The newest thing is now that the door lock on the driver’s side does not always work. Sometimes the buttons of the front and back doors stay up and the car stays open and sometimes not. The typical closing noise can then only be heard from the passenger side. Did anyone have the problem here and know what that could be? See it already coming, that I stand and then everything again Good evening, Pooh.
