Can't save due to an unexpected error (latest version 24.0.1 and macOS Catalina) on a Server

Now I get this. Adobe, I'm getting tired of paying a monthly subscription for betaware.
Solutions?
EDIT: Seems to happen while working from a doc parked on a server. Seems to save ok when working from my local hard drive. After getting the alert, I close the doc, assuming it will revert to the unmodified version, but it deletes the file off the server. Wipes it off.
