After downloading on Android, my game doesn't leave the first screen

First of all, sorry for the bad English, it's not my native language. Talking about the problem, I'm trying to post my game on the PlayStore, I'm trying to do the internal testing phase, I've already made the list of testers, I've made the aab file, I've already launched it for testing, but when my father downloaded and opened the game, don't get out of it
