I measured my frame diagonally and found that it was no longer square by just a little. So I used an ‘extendible’ metal clamp, reversing it to push rather than pull. Pushed from the floor up onto the frame slowly with a towel to protect the frame. It is now square again and swings closed just fine. Might not be your issue, but it was my problem.
