Backup restore has screwed up my system!

I was having an issue with an integration, and had to restore from my latest backup and now my system is completely screwed up.

Most of my Add-ons will not start. I can’t get either the file editor or studio code server to start, so I can’t edit any configurations. My cloud backups are inaccessible, the local backups apparently won’t restore without these errors. I don’t see a way to restore from a copy that I have downloaded.

Is there anything I can do, short of wiping the system and hoping that starting over works?
