Hello there Alexrowe120! Welcome to the forums
I've moved you thread over to our Story Creator Mode Player Support forum. If you haven't already, it might be worth looking at some similar threads here where players were able to resolve this issue. I'd recommend checking out this thread (which developer PinkHusky433 has contributed to) and this thread (where a player encountered the same error as you).
If none of the workarounds in these threads help you to resolve your issue, please don't hesitate to update us!
