What is this loading bug?

I’m making a educational game for my school I work at, but there’s this strange bug that when ever I load the game it just keeps on loading forever and ever. Trust me I’ve tried everything, I’ve tried going out of the editor and going back in, waiting, and just a lot more. How do I fix this?

Hm depending on where it’s stuck in loading that could be an error in the code, or something could be getting stuck in the game logic; could you share the game so we can help?

I think he’s referring to the website editor rather than the actual simulator.
