Short description of error
Sidebar is completely invisible and empty, unless I hide tool settings or the menu.

Exact steps for others to reproduce the error
This is only happening on a specific blend file, I sent it to someone else and it isn't happening for them. The sidebar used to be fine but at some point it just randomly stopped working. I have been on latest the entire duration of working on this file, for about 3 months I'd say. The arrow for the sidebar is there, but if I drag it, it just jumps to about the width of where the sidebar WOULD be, but there's nothing actually there. View > Sidebar also checks and unchecks and N effects this too, but again the arrow is just jumping around and there's nothing for me to actually see. Once I hide tool settings or the menu though, it works shows up again.
