yes, the black screen is caused by the reciever_exported not being implemetned properly into the engine, i told you, to go and set up the thing that fixes it, here: UNREAL 5.0.3 RECEIVER_EXPORTED error in gameactivity.java.template for 34+ api - #2 by araz01
i made this past, this fixes the reciever_exported issue, so you wont launch to a black screen. also, if your app is too big for google play, you’d want to then use google pad, which an updated version, which i also made post about you can use to fix it, just check posts above
