I have version 115.15.0 TB. All works fine except : I tried to delete 805 old messages from Inbox. I received an error saying I needed to under the File menu Empty Trash. I did that by clicking Empty Trash. It said to then Compact Folders. I did that. Then I tried to delete all old emails beginning 7/31/2024 and going back. I still got the same error. So, I deleted them in small batches. So, everything from 7/31 backward is now deleted. But it should have been one simple task. I don't know why this happened.
