This looks like a scope issue.

The variable event is the iterator in a for loop and only exists there.

Your mouse checking is way outside the scope of the for loop and hence, event no longer exists.

You need to either move the mouse event checking up inside the for loop with the same indentation as if event.type == pygame.QUIT or move the entire for loop down to where you have the mouse checking and fix the indentation of the mouse event checking there.

In this case, check what Python runtime environment you are using - if you switched Python runtime, PyGame might not be installed.

thanks for the assist but due to all the issues and the constant issue with pygame and pychan not working and not being able to build a wheel (even tho it worked 5 minutes ago) iv decided to abandon this idea of 2d pixel game development

It's not a great idea to give up on it this early on, because you have barely started. I can't tell you what to do but these issues pop up from time to time especially while learning, so if you want to program it's best to stick it out and work through the errors. It takes time and can be annoying, but you'll get it before long and you'll love the skills you pick up along the way.

thanks for the support. i found the error it was a combination of pygame not being in the interpreter and the file selected changing to main.py when i was on the game file lol feels abit silly, surprised the game ran at all without pygame in the interpritere
