Backup recovery not working

I left my program open overnight. When I came back to it, I had a message come up saying that the previous session closed unexpectedly and if I wanted to restore the previous session. I clicked yes.
All items appeared in my tabs except for the last item I was working on. When I opened the file, it was the original unedited version. Autosave had been set to 2Min. I did a search of my c: drive and found a file that had the correct time stamp on it: C:\Users[myname]\AppData\Local\MuseScore\MuseScore3\scB18180.mscz. It contained the latest version of what I was working on.

Looks like it is not gathering up the backup files correctly after a crash.
