Unable to load plugin

I the following error everytime I launch my game. LogPluginManager: Error: Unable to load plugin ‘AsyncLoadingScreen’. Aborting.

The author said that the code must be in c++ and I can’t find tutorials on how to convert blueprint to c++. Could someone help me with this

You need to convert you’r project to C++, if my memory is good.

To do this, simply add a new c++ class to your project.
