I have the same symptoms. In my case, I turned on developer mode to check the status, and I connected the iPhone to the Mac, and the crash is resolved. (If I turn off developer mode again, the crash will occur.)

FB Number is FB17157281. thank you.

@DTS Engineer We have about six corporate apps. Different employees have different cases of problems. App A crashes, B not crashes, and other employees crash only B apps. Another employee crashes both A and B apps. The difference is that the non-collisioning app is that the new version was overwritten with the existing app installed, and the conflict is when the app was newly reinstalled. (Not sure)

It still crashes after iOS 18.5 beta3 update. FB number is FB17331162.

Yes, I deleted (and removed the profile) all enterprise apps and then reinstalled (and installed the profile).
