This is probably not just you.
On Android, some games (especially PC-focused ones) can sometimes show a black menu because of how Android handles graphics rendering.
It doesn’t usually mean your device is broken. It’s more of an Android compatibility issue that can happen on certain versions or GPUs.
You could try restarting the app, reinstalling it, or testing the game on PC if that’s an option. If it works fine on PC, then it’s very likely an Android-only issue.
Hopefully, this helps narrow it down a bit.
