Problem deploying Android app

[TurboMagic 102]

I have created a small app and when trying to generate the .aab file for the app store I get this failure:
[PAClient failure] failure: E6408 [BT:1.17.2] Error: Files under lib/ must have .so extension, found 'lib/armeabi-v7a/libQRCodeApp.so.tmp0'.

 

Yes, there is such an additional .tmp0 file in that folder and deployment always recreates it.

What is wrong in my project to cause this?

 

The solution offered here:

Didn't improve my situation and it is nerving, that the contents of that deployproj file always seems to be shuffled around/reordered.
