Files and folders are disappearing with Monterey 12.3.1
My files and folders are disappearing from my MBP 2021 and from external drives as I work with them with Monterey 12.3.1. I have recovered copies of a very important folder SIX times because of this. Spotlight search finds the folder correctly, but I have to open it from Spotlight and restore the folder contents each time. I've tried working from the desktop and then directly from external drives, but it makes no difference. They just disappear. I'm starting to hate my new computer. I've used Macs since 1985. Seriously. This is a big problem. I'm wasting tons of time and am very frustrated. Any help would be appreciated.
MacBook, OS X 10.10
