Let me know if you have questions, or something you would like me to try.

I can't reproduce the issue, and the problem doesn't seem to be specific to these test builds so I suggest you continue the conversation in your thread - if/when a fix is suggested let me know and I can try including it for you.

One thing you could do is try to determine when this issue started, assuming it's a coding issue rather than something specific to your MySQL installation - once that test build is known then it might give a clue as to what change is causing the issue. There should be 365 of these test builds online (a mixture of recent Kodi 19 builds from this thread and the rest from the Kodi 18 test thread).   

How many movies and TV shows did you have in your database when you tried to reproduce the issue?
Was your media collection accessed via network /a samba server, or on the local system?
Was your library stored in mysql of some flavor, or were you using slqite?

I have 1780 movies and 7000+ TV episodes, and I suspect the issue is related to larger number of them.
If I load Kodi with just my 4K movies, which is numbering around 20, I don't see this issue.
I also don't see the issue if using sqlite locally.
