Errors compiling first stan model in R

Interfaces
3

Hi all,
Adding some more details. Some other things I have tried…when I uninstall the xcode app, then enter macrtools:: is_xcode_installed() the response changes to TRUE but then when I put the xcode app back in, the response changes to FALSE. I’ve gone through and both my cmdstanr and rstan folders seem to be in the right directory. I have also made sure permissions were changed from ‘read’ to ‘read and write’ but still experiencing the issue. Below is the expanded error message. Any ideas? Hoping to try on a different machine this weekend to see if I have any better results but hoping maybe someone sees something I don’t.
Thanks
