Monogame/Xamarin error with .net8 x86/x86_64 configs for Android <= 28

Question

I am facing with a strong issues with my Monogame/Xamarin app. Monogame is updated to 3.8(.1.303). I migrated from .NET6 to .NET8, and finaly my app is ok. Not completely to be honest, maybe someone knowsthe cause of this behaviour ? I investigated again and again, so now I ask the community :)

I build on the 4 following targets for android 21 -> 34 :

• arm32 & 64 --> no problem
• x86 and x64 --> no problem with android >= 29
• x86 and x64 crash for android <= 28. (I used firebase to get lot of device/target test deployements)

The issue I am facing on during the execution :

• game constructor is fully executed good
• game Initialize -> loadContents --> the code is not reached. So it is located at the start of the app.

To remind, in the native sequence of a monogame app, it is mainly : Activity.OnCreate Game Constructor Game Initialize (Load contents) And a master loop on the update() and draw() methods.

The crash is occring during the starting, and all I did is try catched, and I have no catched exceptions of course.

In //, to complete the desciption, the OnCreate(Bundle bundle) method is also fully executed without exceptions.

I looks like the process is killed after the Game class constructor.

The same code works perfectly for the other configs. Maybe there is something deprecated... but I don't know.

If someone can help me, it will be the first great news from 2 weeks :)

Cheers !
