Project Backups Vanished! + AI Super Scale Crashes Win11

Good evening,
While trying to overcome a glitch with the AI Super Scale's 2x and 4x NVIDIA RTX Video options (they crash my computer and cause Windows 11's blue screen to appear before rebooting my system), I tried accessing the project's backups. I discovered they're all gone! ... Not only for the current project, but for ALL of my other projects. I checked the location in DR's preferences, and it was accurate. I checked my SSD, and all of them still exist.
DR does, however, save new backups of open projects, which can be accessed.
Is this a glitch? How do I access my prior backups, and how do I find out which one is for the project I've been working on?
Also, is the AI Super Scale a glitch, or is it trying to use a feature that my NVIDIA card does not have? All of the NVIDIA RTX Video scaling options worked fine in v19.
Thank you!
Roger
