I've had a Steam Deck for about a year now, but recently my Steam Cloud is having an error on my PC, where any games that I've played on my deck for any amount of time, will have the Steam Cloud Error message. I've tried numerous videos and guides online, but nothing works.
I've attempted:
Deleting the "userdata" folder in the Steam folder
Verifying the integrity of the game files
Uninstalling the games on both my Steam Deck and PC
Simply turning the cloud sync off for a little bit then back on

It's frustrating, and I'm about to try uninstalling and reinstalling steam on my PC. Any help would be appreciated.
