Debugger Assert

[mlancione]

I get the following Mono debugger assert when placing a breakpoint at line 34 of the attached AppDelegate.cs and stepping over.

error: * Assertion at /Users/runner/work/1/s/src/mono/mono/mini/mini-arm64.c:6876, condition `native_offset % 4 == 0' not met

Test Environment:
iOS Simulator running on MacOS 14.7 on Apple Silicon

Steps to reproduce:

1. Place a breakpoint at AppDelegate.cs:34
2. Run application with debugger
3. Step-over from breakpoint

Hi, @mlancione ! Yes, I can reproduce it. I will create an issue in xamarin-macios repository. Maybe people from there will help us with this error.

They've already helped me once: dotnet/android#8653

dotnet/runtime#110016

This caused me a headache with Apple submission as it failed on an iPad test of theirs.

I did some testing and found that when I downgraded the following from Version 9.0.3 to 9.0.2 the problem went away:

Microsoft.AspNetCore.Components.Authorization
Microsoft.AspNetCore.Components.WebAssembly.Authentication
Microsoft.Extensions.Caching.Memory
Microsoft.Extensions.Hosting
Microsoft.Extensions.Http.Polly
Microsoft.Extensions.Localization
Microsoft.Extensions.Logging.Debug

Not sure which is the actual culprit although I suspect Polly and Localization are probably not... but at this point, they are all matching each other and seem to fix the problem.

It looks like this issue has finally been fixed in mono:
dotnet/runtime#118458

Does .NET Meteor need to be updated with this fix or do we need to wait for a new .NET for iOS update to use the latest mono code?

It looks like a part of the Xamarin.iOS workload. I think that we need to wait for the new dotnet version.
