UE 4.27.2 android app shows black screen (Google PAD)

Hey,
I’m trying to roll out my mobile game on the play store for closed testing.
The game size is roughly 700mb, well over the APK size limit of 150mb, so I am resorting to using the Google PAD plugin to generate an .AAB that google will accept.

But the plugin that I NEED to use seems to cause a black screen upon launching that never changes, the app doesn’t even stop responding.
