Unknown Type Issue

Building any C projects in Xcode is giving me the following unknown type errors. I tried this with the basic C project hello world template to ensure it was happening with all C projects. I am currently on Sonoma 14.0 and running Xcode 15.0

Any ideas on how to resolve these errors?

I would: run disk first aid, reinstall Xcode, reinstall Sonoma, in that order.
