Startup project crashes after splashscreen on iPadOS and .NET8.0 in release mode

[gem11]

Description

I want to point out the the bug reported in #19522 ist still occuring. Please reopen that issue and investigate. To my understanding it is not possible to get a working iOS release build of the Hello World .NET Maui app or any other .NET 8 Maui app. How shall I investigate the error in my app if even the offical template crashes?

Steps to Reproduce

1. Start Visual Studio 2022 - Create a new project
2. Select template .NET MAUI App
3. Leave all defaults, ensure .NET 8.0 is selected.
4. Pair to a mac
5. Connect an iPhone or iPad to the local machine
6. Build and run the app in relase mode on the iPhone/iPad

No response

Version with bug

8.0.20 SR4

Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

7.0.96

Affected platforms

iOS

Affected platform versions

iOS 17 Visual Studio 17.9.6

Did you find any workaround?

Using .NET7, but is not feasable for my project, as it uses .NET 8 features and I would need to change the implementation

Relevant log output

This crash log is from my app, not from the hello world app, as the only log I could get was from a test flight release crash report:

Verified this issue with Visual Studio17.10.0 Preview4(8.0.20 & 8.0.14), can repro on iOS local device and not repro on remote device, local device ,it can only deploy apps that use the debug build configuration, please refer ro https://learn.microsoft.com/en-us/dotnet/maui/ios/hot-restart?view=net-maui-8.0

[gem11]

Indeed, when building and running in relased mode to a connected ios remote device, the app starts. However I tried to upload this build to testflight and after downloading the app from there it again crashed with the same log as I put above. So I still am not able to publish a working version to app store.

I also see this on both iphone and iPad 12.5.7, but my app works on iPhone6 iOS 15.8.2. Is this only iOS 12?

[mdbill]

This did not help me (but I learned my problem is not related -- see below)....

<PropertyGroup Condition="$(TargetFramework.Contains('-ios')) and '$(Configuration)' == 'Release'">
    <UseInterpreter>true</UseInterpreter>
</PropertyGroup>

[mdbill]

Nevermind. My Maui apps are all working on all iOS versions. Live in the app store too. I was calling
StoreKit.SKAdNetwork.UpdatePostback(0, _ => { }); which isn't supported before iOS 15.4
