UPDATE: I'm guessing that there's a file in the system that went corrupt during storage. I was able to find the USB stick where I backed up the Syntec system in 2018. But when I try to restore the system using the .zip backup file, it loads for a little, then says "restore operation failed". I created a new backup from the system today and compared it to the one I made in 2018, it has the same file structure and everything, so I can't find the issue. I'm able to restore using the backup I made today, it gives me no errors, but the backup from 2018 gives me an operation failure.
