Same here, located in Greece. At first I thought it was a caches thing, then I thought I might have somehow messed up the system fonts, then I hoped that I didn't have to format my mac. At least I now know I'm not alone in this. Awaiting for a fix...

I have exactly the same issue, while playing around with Xcode 14.1 on Ventura. Code that run perfectly fine in Xcode 13x and Monterey, now produces errors such as these mentioned here.
