Hi. I’m learning 2D Beginner: Adventure Game on unity learn. I need to download starter pack and open it on unity hub but when I tried this I face with that error “Project failed to open, This project is not valid”
The file you downloaded it’s called ***.unitypackage?
In that case, you need to create a empty Unity project from Unity and then drag and drop that file.
You have the detailed explanation on how to do that in the tutorial.
