A sudden exit during gameplay without any warning

This may happen if the game app contains bugs – or if your phone runs out of RAM, and apps do not "voluntarily" return the amount of memory that iOS demands.

If you are running browsers with lots of tabs open, or other apps that might be using a lot of RAM, you could close them before running the game, and see if that helps.

Another cause of crashing can be if you have a battery whose Battery Health is below 80 percent - a battery that needs to be replaced, and that cannot provide all of the power needed at moments of peak demand.

Games Crashing on iPhone 8:

Update your iPhone:

What's the iOS version in stalled on your iPhone? iOS 16.7.13 is the most-recent released version iOS that is compatible with your device. If not install ten, then update to it. To find out, Go to: Settings > Advanced > View the iOS Version.

IMPORTANT: Back up your iPhone to a computer before performing the update. That way, you'll have something to restore your iPhone from, should anything go wrong during or after the update.

Troubleshooting a Crashing App:

A. Delete ALL VPNs:

Have any VPNs installed? If so, delete them.

B. Perform with a Restart:

Having just installed any update, perform a restart: Restart your iPhone - Apple Support

C. Contact the Developer:

You may have misconfigurations. So, contact the Developers of these apps. You'll find their Contact Us info in the app's site of the App Store.

Assuming the backup and reset and restore does not work…

Report the app crashes to the app developers, and particularly if you can reproduce the crashes.

They’ll know about most bugs and limits.

That version is no longer signed by Apple so will not pass the verification step when attempting to install. iOS 16.7.12 is the latest version, but currently 16.7.13 would still show in Software Update, so it is not possible to update at all until the issue with that release has been resolved.
