Error "could not save as because write access was not granted" in Photoshop 2020 and macOS Catalina

[DavidO$]

When I try to save an image in Photoshop I get a message

Could not save as “IMG_9257.tif” because write access was not granted.

I also get "file could not be written" when I try to save in Lightroom Classic

Can any body help me I am running the very latest Catalina update on a Mac and the latest update of Photoshop.

If that can help... I work on photoshop 23.4.1. None of the advices worked for me (full disk access, reset preferences...), until I stop the deskop folder backup I had with dropbox ! It works like a charm now.
