InDesign version info attached (Mac OS 10.15.7).

I've been dealing with persistent crashing while trying to open ID files. For certain files, the beach ball of death appears for an extended (and sometimes endless) period, at which point I force-quit and open the file again. On the second attempt, the file always opens properly. This happens with most, not all, ID files — so I literally have to restart ID 30+ times a day. No fun.

I've reset preferences and even reinstalled ID from scratch, but no luck. One thing I noticed is that if I move the ID file to the desktop, it opens fine on the first try. I did some more experimenting, and now it seems that if one of the file's parent folder names begins with a number/pound sign, the error/hang occurs — however, when I remove the pound sign, the file opens fine (I begin my project folder names with the project number). In my case, the relevant parent folder is three levels up (e.g., #80-21 Project name > LAYOUTS > v1 > Project file.indd).

Soooo, I'm not sure WHY this is happening, but it may be an easy fix, and I'm guessing (?) this may be happening to other users as well. Hope this helps — fixing this would be a simple but major usability improvement on my end. Thanks.
