On the slide frame, there are slotted bolt holes. They can be loosened to allow some movement to get at your problem. The slots on one side are probably not long enough to make up all the gap, so It may require adjusting both sides and then the cylinder stroke may need adjusting too.
It can get complicated and take some fussing. Consider a good dealer to have it done. Hopefully the frame is not bent badly.
I had a similar issue with a slide. Not as big a gap as you have. A cupboard door was left open when closing the slide. I was able to get it back to normal.
Good luck with it.
