I don't think this problem has been fixed, even up to 3.0.4. I just tried the following short snippet in LINQPad using FastExpressionCompiler 3.0.4 and Mapster 7.1.5:

class Test
{
	public string? TestString { get; set; }
}

void Main()
{
	TypeAdapterConfig.GlobalSettings.Compiler = exp => exp.CompileFast();
	_ = TypeAdapterConfig.GlobalSettings.Default.MapToConstructor(true).PreserveReference(true);
	
	var test1 = new Test()
	{
		TestString = "Test"
	}.Dump();
	var test2 = test1.Adapt<Test>().Dump();
}

I get an InvalidProgramException with the message Common Language Runtime detected an invalid program. The stack trace is:

   at (ArrayClosure , Object )
   at Mapster.TypeAdapter.Adapt[TDestination](Object source, TypeAdapterConfig config)
   at Mapster.TypeAdapter.Adapt[TDestination](Object source)
   at UserQuery.Main()

Please reopen this and look into it. I have had to temporarily exclude using FEC in my programs using Mapster as a result of this.

@CyberBotX I will look into this. Thanks for posting.
