hey, guys, I am building an application for windows and android, the application works fine in the editor but when I try to build the application for windows I get three errors (I haven't tried to build for Android). I don't know why I am getting this error for the first error I checked my plugins folder the UnityEditor .dll file is present, I don't know why I'm still getting this error. thanks in advance.
