Changed prompts don't run (no permission)

When I follow along the Guidelines lecture, the original prompts run fine, but when I change anything in the prompt (even a single character) and try to rerun, I get the error:

PermissionError: Project `proj_OXEC08aO6rKYJweAEj6Aae5D` does not have access to model `gpt-3.5-turbo`

How to fix this?
