Android Question Imageview Exception

Maybe it's solved, but then I don't find it

I have a simple Mediaplayer App and it works fine on Android 10 with a Item SDK Version 28 in the Manifest Editor.
Now I copied the App on an old Phone with Android 4.3 , it doesn't work. I change the Manifest Editor MIN Sdk Version to 4 and starts the project in a Debug Session .
Load Layout throw an Exception "btPlay not initialized" btPlay is a Imageview an the Bitmap is assigend in the Designer.
I remove the Bitmap-Items in Designer and try to assign at runtime ... I get the same Exception (Imageview not Initialized)
Now I don't assign any Bitmaps, I have only white ImageView's without Images ... and the App runs fine.

I updated B4A from version 10.5 to 10.6 without any change.

A prior Version of B4A or SDK or whatelse was able to start it. I found an old app , build with an old version of B4A and I can see these Bitmaps.

Any Idea ?
It's not really important for a simple Mediaplayer on an old Smartphone to play MP3-files in my garage, but maybe it can be important for another App that has to run on an old Version.

and the b4a code is the
Activity.LoadLayout("mplay")
in the Sub Activity_Create
and it crashes at first time.

and, as described above, it's an old software , I create it for years to use an old smartphone in my garage as mp3 player. Now I want to change a little bit, use the new b4a and it chrashes.
