Photo Library doesn't work in Pictures folder, but does on Desktop
I'm on a Macbook Pro, running Sequoia 15.1 (recently upgraded) and I've been having issues with my Photos app for quite a while, even before upgrading my OS. Initially the issue was that photos from iCloud were not syncing. I tried repairing the app, nothing. I created a new library and it would just get stuck on "Syncing from iCloud" or "Restoring from iCloud" but never showed any images or any actual attempt to restore or sync, just big black text for days with no updates.
The original library and the new ones I created were all created in the "Pictures" folder on my local hard drive, as that is the default. Today, after trying literally every thread on this topic I could find and having no luck, on a whim I created a new library on my desktop instead of in the Pictures folder. When I made that the system library and turned iCloud back on, everything loaded super fast and is totally up to date with iCloud.
So my question is, why will the library not work when stored in the Pictures folder, but will work from the desktop? Did something happen to my Pictures folder? I did have some trouble where things were syncing to iCloud drive in a way I didn't want them to, but I thought I put everything back as it was. And does it really matter where the library file lives? Can it just stay on my desktop?
