Bounce between start/end markers not working in PT 2023

Hi all!

Hoping someone can advise as I'm not experienced enough with code. Been using the script attached for a few years on every project and it's great, but it's stopped working with my M1 Mac Studio/Ventura/PT 2023.6. Tried similar forum post codes but getting the same issue.

Simply meant to bounce between Start/End markers and copy the project name. The error is:

"Couldn't locate AxElementArrayIndexedItem (Line 25)"

Any help very appreciated!
