Hello,
I am running into an issue where after importing the plugin, if I try to make a C++ class or compile, I get the error that the plugin is not available.
I have checked that the plugin is installed. Before I made the C++ class, I was able to make the Arduino I have work with Blueprints. The moment I made a blank Actor class in C++, I started getting that error.
What's more, now I find myself unable to even open the project.
