MAUI Mobile App crash on TestFlight

If your MAUI mobile application work fine on iOS device in debug mode but crash on launch when published with TestFlight, try to edit MAUI Visual Studio project file.

In Release for iOS configuration add the following two lines:

<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Release|net7.0-ios|AnyCPU'">
...
...
     <MtouchLink>SdkOnly</MtouchLink>
     <UseInterpreter>true</UseInterpreter>
     <MtouchExtraArgs>--optimize:-static-block-to-delegate-lookup</MtouchExtraArgs>
</PropertyGroup>

In my case the error from AppCenter is:

libsystem_kernel.dylib

libsystem_c.dylib
