Since version 21.0.1, some videos stop playing after 30 seconds.

I run Kodi on Formular Z10 Pro MAX 4K Android.
Last week, Kodi was automatically updated to version 21.0.1. Since then, some videos (not all) will stop playing after about 30 seconds and Kodi will return to the overview of videos. This also happens with videos that could previously be played.
I haven’t been able to find anything that solves this.
