App Stopped Working, Black Screen on Android

Hello, I’ve made an app and built it for android using these settings:

I uploaded it on google play for Internal Testing and one tester downloaded it on his phone, everything was working fine, 1 month later with no updates, no touch at all to anything, the app stopped working only on his phone, the other testers have the app still working.
Basically he gets black screen when he opens the app and it doesn’t seem to load, everything was working fine before, nothing changed. He tried to uninstall and install, i tried building again updating android sdk etc… but still he’s the only one who doesn’t get it working.
What could it be?

Other thing, I’m in UE 5.3 and even though the tests of google play dashboard says the mobile devices working are more than 8k, the phone of my girlfriend is showing as compatible, I can install the apk if I download it on the phone but if I try downloading from the store of the internal test it says that the app is not compatible for that phone.

Is that because unreal engine 5.3 has less supported phones and I should go back to UE4? If that’s not the issue since it seems to work perfectly with apk download why is that?

Hey! You ever found a solution?
