MAUI App Crashes in Release Mode For iOS When Using Query/Command Pattern - AOT Compilation Issue

[bober20]

I'm developing a MAUI application using MediatR and the Query/Command pattern with Handlers. While everything works correctly in debug mode, my application stops responding when I attempt to send a query in release mode. I believe this is related to Ahead-of-Time (AOT) compilation trimming necessary code.

The whole project is available in my repository named Test (https://github.com/bober20/Test)

What I've already tried:
Explicitly registering each handler in my dependency injection setup:

services.AddTransient<IRequestHandler, Handler>();
Configuring the linker in my project file:

true link true false true false

I get the following error in my debug mode:
MauiApp1[3132:1224716] error: * Assertion at /Users/runner/work/1/s/src/mono/mono/mini/mini-arm64.c:6876, condition `native_offset % 4 == 0' not met

Has anyone encountered similar issues with MAUI release builds and query/command patterns? What solutions worked for you?

"If your .NET MAUI iOS app or ARM64-based Mac Catalyst app works correctly as a debug build but then crashes as a release build, try enabling the interpreter for your app's release build. It may be that your app, or one of its libraries, uses a feature that requires the interpreter."
