Kirby Blank Panel no errors

Hey I’ve just cloned some one on my teams Kirby repo and everything’s running fine on their machine and remote but on my local (MAMP) I’m getting a blank white panel.

The only error I’m getting is in the console

Uncaught SyntaxError: await is only valid in async functions and the top level bodies of modules

from app.js

Any thoughts on why this might be?

Thanks in advance,
