There was one other guy reporting this behavior (also on Windows), but I couldn't track it down. Even from the logs, I saw, that addon did exit, but Kodi still reported some problems.
But at the end, it was related to Plex addon.  

So, is this a fixable item or just something I have to live with?  I really would like to continue using this, but, not with a reboot after every use.  Thanks.  

I'll spin up a Windows 10 VM, and try to debug it.
But if you could enable debug logs, and send it to me, that would be very helpful 

I can certainly do that for you.  Which logs exactly would you like?
