Hey Idfk10, sorry you're having issues launching the game. Sometimes it does take a while to initialize, however, if it persists, closing down the launcher and restarting usually helps.
Also, if you're updating from a previous version, make sure the old RPA file is deleted, as it will try to unpack everything at once.
If that still causes issues, can you make sure all the necessary app permissions are in place and try reinstalling the launcher?
Hopefully this helps o/
