I get the following messages in my iOS crash report:
SharedCodeProject_MyClass__Updated__301_MoveNext (in MyGameiOS) (<unknown>:1) System_Runtime_CompilerServices_AsyncMethodBuilderCore_Start_TStateMachine_GSHAREDVT_TStateMachine_GSHAREDVT_ (in MyGameiOS) + 388 MyGameiOS_SharedCodeProject_MyClass_Update_Microsoft_Xna_Framework_GameTime (in MyGameiOS) + 184 -[iOSGameView doTick] (in MyGameiOS) (registrar.mm:13304)
I have uploaded my iOS build on TestFlight and then installed it on my iPad. My game always crashes 1-2 seconds after I opened it on my iPad. It only crashes in release mode and not in debug mode. It also crashes when I remove the push notification code in Program.cs where I check if push notifications are enabled or not.
Does my game crash in MyClass.cs in SharedCodeProject? I don´t know what all these messages from the iOS crash report mean and it is difficult for me to find the issue because my game crashes in release mode and I don´t know how to log the error when my game is in release mode.

Based on your code, the
MyClass.Updatemethod can be the source of the issue. This suggests that the crash is occurring in your game loop, specifically when thedoTickmethod is invoked, which may callMyClass.Update. if you have thisUpdatemethod, please check do you lack theawait, use try/catch to wrap the code in theUpdatemethod.Please right click the project, choose properties, select the iOS, choose the Build, find the release & net8.0-ios, change the Link Framework SDKs Only to the Don't link , then release your application, will you have this issue?
What is your .NET version? Please update your nuget package to the latest version.
Please edit your Question to add above question and tested result.

I use Target framework .NET 9.0 in my iOS project.
This solved the issue. I changed Linker behavior-->Release to Don´t Link.
I changed it from:
