UE 4.27.2 Packaged android game keeps crashing on startup

Im not sure what im doing wrong. I package the game, i send the arm64 version to my phone, install the apk and when i launch the game i see the splash screen for a tiny moment, then the game crashes constantly, then it says that the application keeps quitting unexpectedly.
Im not sure what the reason could be. Maybe i have to use the .bat file to install it? Idk. My phone is the OnePlus 8T if anyone wants to know. Any help would be appreciated.
