Do you have XCode instalied? It looks like it can’t find the sdk directory for it. ---

Probably you had another version of “cli-xcode”. For example, if you try some developer stuff like homebrew or just “xcode-select --install” ,which installs little bit different SDK (more regular for compile command line apps). Anyway try to install official Xcode first and run this command in terminal after: $sudo xcode-select -r Let me know if it helps ---

Can confirm that the sudo xcode-select -r was what fixed it for me. ---
