I had that problem too and it was an easy fix for me, you should check this.
The oven is screwed to its metal frame on its side and is held in with 2 screws, one of them was loose, making the oven fall into the frame and the door got stuck when pushing the open door buttonm.
I removed the screws on the frame to the cabinet, pulled out everything and replaced the screws holding the oven to the frame with stronger ones.
