Help with Library issue

Plex Media Server
1

I just installed a PMS on my mac and am working to add a library. When I choose the external drive where the media lives, I can see folders I’d like to add, but when I try to add them I get the following message.

“Your changes could not be saved.”

Any help would be great and thank you in advance.

Seems like a familiar issue with these recent PMS releases, had this now with 2 of my builds with no real understanding of how to fix.
