Mac catalyst apps must be compiled to native via the AOT compiler server. AOT has limitations, in that the full .net runtime is not supported. emit is the most common missing feature that causes issues. you appear to be using code that uses the emit feature which AOT does not support. lots of libraries (serialization, linq, etc) use emit to generate dynamic code which is faster than reflection. see:

What do you mean, my code is not supported ? Is connected to how I publish the app ?

can't see your code to tell you what is not supported. did you enable the maui interpreter?

I used arm64 Did you mean that code <PropertyGroup Condition="'$(RuntimeIdentifier)' == 'maccatalyst-arm64' and '$(Configuration)' == 'Release'"> <UseInterpreter>true</UseInterpreter> </PropertyGroup> what about Intel no need for intererter?

Wenyan Zhang (Shanghai Wicresoft Co,.Ltd.) 29,206 Microsoft Vendor

Try the following:

<PropertyGroup Condition="'$(RuntimeIdentifier)' == 'maccatalyst-arm64' and '$(Configuration)' == 'Release'"> <MtouchInterpreter>-all,MyAssembly</MtouchInterpreter> </PropertyGroup>
