One of my Makecode Arcade Projects wont open

Hello there! I recently built a project using one of the tutorials, (Collect the Clovers) and I wasn’t able to load it because it gives me an error saying “There was an error loading this project”. I was wondering if there was a fix to this because I need this to be fixed soon. This is for an entry to a Tech Competition in my city.

Try making a copy of it and open the copy.

It wont work. It just doesn’t duplicate.

I have however remade the project and its working fine for now.
