Hi @Jeff A. King ,
Welcome to Microsoft Q&A!
According to your description, I can’t reproduce your issue on my side. Maybe there is a background VS task running. Have you installed some extensions in your VS 2019?
I suggest you update your VS 2019 to the latest version and temporarily disable some third-party extensions from Extensions > Manage Extensions > Installed > select and Disable.
Meanwhile, you can try to disable Save AutoRecover information every: in Tools > Options… > Environment > AutoRecover.
If you still encounter the problem, you could report it to product team engineers by selecting “Help” menu > Send Feedback > Report a Problem.
Sincerely,
Anna
