I updated to the 12.3 beta the other day (by accident, I didn't realize or know how I ended up in the beta program for Mac), and I realized my Documents folder was empty. I thought perhaps it is a visual glitch and put another file in there, then rebooted, and that file is now missing too on reboot. Spotlight and Finder can't find any of the missing files so I believe they're being deleted on reboot now. Hope this is fixed soon.
