There is no "Save messages to file" in 113.0b5 on Mac, which version are you seeing it on?

I'll try and catch any errors next time it happens, but I certainly saw it 9 days ago.   It doesn't happen often, and is different from the possibly related and still common problem where the list takes a LONG time to update after deleting. 

Typically I'm working in a window which is a saved search (all messages in my inbox where the sender isnt' in one of my address books), and then I'm using Quick filter to just show Unread ones, then I'm scanning through them quickly hitting delete or "J" to send to junk.  I don't if that combination is what is slowing it down, or occasionally causing the update not to happen.
