Unity Game Crashes After Unity Default Splash Screen

My Unity game is crashing after the Unity default splash screen when I exported it for the IOS platform. The game runs smoothly on Android and Windows but crashes in IOS devices.
The Xcode version is 14 and the IOS version on iPhone is 16. This XCode version does not support IOS 16, so is the issue due to the version conflict or some other issue?

this one says Xcode 14.0.x supports iOS 16.0, is that the specific version?

can you see any errors if phone is connected to mac? or are you building locally to device?

What Unity versions you are using?
There might be multiple reasons for that to narrow down the scope, can you please share the crash reason and stack trace details from Crash Report ips file from Console application ( using Development, Debug iOS build ) ?
