It seems like the issue you're facing is due to the game needing JIT (Just-in-Time) compilation, which isn't currently supported by Sideloadly on the latest iOS versions like iOS 18. The game is crashing because it can't access the JIT features it needs to run properly. While Sideloadly doesn't support JIT for these new iOS versions yet, you have a couple of alternative methods to enable it. You can find more detailed tutorials on Google, but here's a brief overview:
Method 1: Using StikDebug
This method requires two tools:
StikDebug: You can Download Here
idevicepair: You can Download Here
First, install StikDebug and pair your device using idevicepair (you can find a tutorial on how to do this here). Once everything is set up, open StikDebug, and then launch the game from within the StikDebug app. This should enable JIT for your game.
Method 2: Using SideStore + Live Container
This is another popular method. You'll need to install your game through Live Container within SideStore. After the game is installed, make sure to enable JIT for it before you open the game. https://sidestore.io/#get-started https://github.com/LiveContainer/LiveContainer
