Execute JS in browser not working (permissions?)

I convinced my friend to purchase KM. I have a number of macros that involve executing JS in the browser (mostly testing in a loop for DOM element). Regardless, the macro runs perfectly on my laptop, but not on the new machine. Both are M1 MacBook Air.

Am I running into a system permissions issue or something like that? Any ideas to troubleshoot are appreciated.

Have you Allowed JavaScript from Apple Events?

I had not. Thank you for pointing me in the right direction.
