I don't think it should be possible to delete itself, it's not an action of the computer or an antivirus ? But I'll check to add security when there is a file deletion. And recently opened file, you mean the recovery files ?
Recovery was perfectly ok and I was able to recover my files by using that. By recently opened files I mean the Projects tab at the Files | Projects | Folder - they still appeared there, but upon clicking them it says the file is corrupte, and when I went to where those files were previously saved the file was gone.
Only antivirus on my computer is Windows Defender.
