Runtime Error "Could not find part of the path" (Mac)

Hoping someone can help me with an error im receiving. Im currently doing a University unit that requires the use of HB tools (im new to this and not entirely sure what im doing).

I get the runtime error “Could not find part of the path”. I followed a YT tutorial but for some reason it doesn’t work for me. I am on Mac incase that is an issue? my teacher couldn’t help me either.

I looked through other forums before posting but I couldn’t seem to find the exact case of it happening to someone else.

Any help would be great.
Kind regards,
