I don’t know how much of a help this will be, because I’m a newb myself, but, I’ve been following th tutorials and had the same problem.
If you’re following this tutorial:
When you get to the point of importing the Viking project, it says untick the Vikings Demo folder. You also need to uncheck all the assets under the project settings tab.
When I didn’t import those, I didn’t get the pinkscreen error.
So, in the other demos, I guess you need to check something in project settings. Or if you’re importing, don’t import the settings.
I know this isn’t the best answer, but hopefully it’s a place to start!
