@DownToCode Thanks again for your quick and helpful response.
Short answer is that it worked! Installed VS 2019 and recompiled and cooked and voila, packaged.
Strange though as it worked fine in the project for 4.24. I was installing the plugin from the Epic Launcher rather than copying and pasting.
It was a C++ project. I use added nodes into my menu BP. Even with VS 2019 installed I still can’t click on the node and see it in VS studio. It says it can’t find the file, but it works and it now packages, so whatever.
Again, thank you. A+ Dev in my opinion. Have a great weekend.
