TMSFNCBloxControlRegisterElements Access Violation under Win64

The following code compile and run fine as a VCL application under Win32, but creates access violation when running under Win64:

procedure TfrmMain.TMSFNCBloxControlRegisterElements(Sender: TObject);
begin
RegElementList.Clear;
RegisterElement(TANDBlock, '', 'AND', 'Logic');
end;

I'm running RAD Studio 10.4 with Update 2.

Attached is a sample project that shows this behaviour:

Hi,

We couldn't reproduce this issue here, both Win32 & Win64 are running correctly. Are you using the latest version?
