My iOS app crashes after installation on a device through distribution, but it works fine in debug mode. How can I check why my app crashes after installation on an iPhone? I am using the latest .NET 9.0.
What variation of crash was observed?

Do you install the app from Appstore? Or you just upload the app to appstore connect and install it from TestFlight?
If you test the app from TestFlight, you could find the log on appstore connect portal.
install app through firebase distribution.
i also install app through both Firebase and TestFlight but not able to see any crash but when open app after some time the app will close automatically.

this error log iOS device Analytics
Form the log, we can see there is an exception "exception" : {"codes":"0x0000000000000000, 0x0000000000000000","rawCodes":[0,0],"type":"EXC_CRASH","signal":"SIGABRT"},. Are there any other error messages? Besides, what's the Xcode version when you publish the app? I saw the iPhone OS 18.2, do you have the same issue on other iOS devices?

it looks like you .net code is throwing an error when it called back by UI framework after a scene transition. You probably need to add more explicit error handling and logging.
