I also have this issue on Android 12. I've RetroArch (AArch 64) and picked mGBA for Gameboy advance.
The mGBA core has been downloaded already in RetroArch.

But when YuNo opens or switches the RetroArch, it just hangs on a black screen until a pop up asks because RetoArch is not responding so you want to Wait or Close it.
