Problem App inventor, 2x Samsung s5 (Android 5.0 ) is working, Huawei Android 8 not running


I have 3 phones, 2 x Samsung with Android 5 or 6 and 1x Huawei with Android 8.
My app that I created with app inventor2 works on the 2 Samsung phones, but not on the Huawei. It doesn't work on a notebook with Android 8.1 either. Is there a known problem with the different versions or there are already solutions or ideas on how I can narrow down the problem.


You should start and tell about the app you are making. Assets, components, extensions, size, etc.

Post an aia if possible.
