All my stock parts won't load in

[ticonderoga7]

I play on a MacOS Mojave v. 10.14. 3, my "game data" folder has the squad file with all the parts in it but the game won't register their existence once the game has loaded. All the stock parts just don't exist when I'm playing. This happened after my computer updated. I'm not sure how to fix it. All my mod parts load in just fine though.

Please provide a log (upload it on a file uploading website such as google drive, pastebin or dropbox) and try verifying steam game cache.
