If the nightly does not improve it can I safely go back to 9.2.2? And if so is it just a matter of downloading and installing that version over the nightly?
I have also been having this problem for a long time. It happens with my N2s (and Rpi2s I used to use). To prevent the crash, I make sure I exit back to Kodi’s home screen and then move the active selection off TV (like to Movies or TV Shows). I posted the issue on the Kodi forum, but developers haven’t been able to replicate to resolve.
I’ve been doing this since your suggestion and not one crash, plus it has removed strange entries I had in kodi.log when the box was not being used. What a weird fault that only occurs when the box is not in use and a particular menu item is the focus. It also explains why disabling TvH client the crashes also stopped.
Thank you for your input, at least I know how to stop it, but it would be nice to know the cause.
