Qt 6 for macOS Ventura 13.0.1

PeterH.73

My Qt 6.3.1 project was building fine on macOS Monterey 12.6.1. After upgrade to macOS Ventura 13.0.1 Qt Creator cannot find 'wchar.h' which causes the build to fail. I can't find any answers in the forums although I did follow some older recommendations to update the command line tools on the mac (which didn't fix the issue). Xcode is up to date and building a simple cpp app from the command line that includes 'wchar.h' works fine. Any suggestions would be appreciated.

Hi, I had a similar problem when upgrading to Ventura 13.0.1. I solved it by updating to Qt 6.4.0, deleting the old build folder and deleting the old .pro.user file for my project.
