I am trying to load the sample plugins in C++ on Illustrator. The ones with UI functionalities are giving me problems (DrawArt, MarkedObjects, ScriptMessage, EmptyPanel). Some show up in the menu but they do not work. Some do not even show up in the Illustrator menu.
I am on Windows and I am using Visual Studio 2019, Illustrator 25.2.1 and 2021 SDK.
