Problem with AAB file and AR Foundation

Hello everyone. I am writing about a problem I am having with an augmented reality app.

We are using Unity 2020.3.23f1 and AR Foundation v.4.17 (AR Core and AR Kit also v. 4.17).

The problem is related to the build format: when we export to APK the app works and there is no there are problems with augmented reality. Whereas if we export to AAB to put it on the Google store the app freezes when the the augmented reality features are activated: the camera view is not displayed, the screen goes black and the app freezes preventing the user from being able to move forward, then crashes.

I have read about problems related to AR with the AAB file when the Split Application Binary option is enabled. But this is not our case: this option is not enabled.

Also I read that someone proposes a solution by deleting some files from the Library folder of the project Unity when we go to build in AAB after changing the target architectures (arm64 and armv7, we enabled both)

https://forum.unity.com/threads/android-il2cpp-build-crashes-while-select-both-arm64-and-armv7-architecture.1113217/#post-7493641

Unfortunately, this solution doesn't work either.

This situation is frustrating as the APK works perfectly but we cannot put the app on the Google Store because this I accept now only AAB.

Has anyone experienced something similar? Do you have any solution to propose?

Thanks for your help
