Sorry to hear that, please check out the comment thread a little below started by "TheLordOfCinder" there seems to be a few users suffering from instant crashes due to the way godot 4 renders and exports the game.
But you said it never gets past the loading screen? It might be that your device isn't powerful to run the game, can you tell me the specs of your device and the operating system you're using so I can double check if there's a different way to help make it run?
