This error occurs BOTH in 4.18 & 4.19.
Firstly I created a Plugin named “CWButton” with a Blank template for my project “MyProject” and it succeeded.
Then I tried to add a Actor class in Plugin module and make sure all actor paths right. It failed.
I have searched for the answer many days but found nothing. Anyone knows this issue ?
PS.
change the Solution Configuration in Visual Studio from Development to Development Editor DOES NOT work for me.
