Syncing Failed With Error Code -516

On my desktop (Mac Studio M1 Max), I opened Premiere to sync my settings I uploaded 2 days prior from my laptop (Macbook Pro M1 Max). But I was greeted with an error message:

Syncing Failed With Error Code -516

Not sure what this means, and it happens when I try to download and upload settings. I couldn't even find a forum with a similar error code, but I tried the basic troubleshooting steps outlined below, but to no avail:

1. Restarting my computer
2. Cleaning my caches
3. Backing up my Adobe Premiere settings in my documents so it can create new folders to try and re-sync from there
4. Uninstalling/reinstalling Premiere
5. Uninstalling via the Creative Cloud cleaner tool
6. Manually migrating my settings from my Macbook to my Mac Studio, which DID bring them over, but I want to be able to sync settings in case I make any changes or keyboard shortcuts. 

Frustrated, I contacted customer support who transferred me 3 times because they couldn't figure it out either, ultimately leading to them disconnecting the call. I come to my Macbook (which they haven't remoted into or done any additional work on) to see if I am experiencing the same issue (this Macbook is signed onto a different iCloud account but the same CC account, and I use it primarily for work.) I come to find that when uploading settings, the same error happens! There wasn't anything I was doing on my Macbook that should cause that issue as it was working two days ago when I uploaded my settings. 

Before disconnecting, the CS agent tried doing all sorts of setting changes with permissions (this wasn't an issue 2 days ago), even going as far as enabling my root user. Weirdly, when I did log into my root user, I was able to sync my settings, but am unsure of what to do now.

I don't want to make a whole new user account to resolve this. I don't want to have to stay on the root account (security risk), and I find it so hard to believe that two DIFFERENT machines on two DIFFERENT accounts had the same issue that cannot easily be resolved. Is there something I am missing? Something I should do in my root user account to fix these permissions? It's going to be a hassle explaining to IT why they need to log into my Mac's root account to fix this weird issue on my Adobe account. Customer service was less than useful here, and I hope I'm not the only one experiencing this odd issue. 

Any assistance would be greatly appreciated.
