[M1 Mac, Ventura 13.3.1, clang 13.0.0]
MacOSをMontereyからVenturaに上げるとコンパイル時に以下のエラーが出るようになりました。
fatal error: 'stdio.h' file not found
#include_next <stdio.h>Command Line Toolsを入れ直してもダメでXcodeを削除したりしているといつの間にか正常になりました。Xcodeを解決後に再インストールしても問題ありませんでした。MacOSをバージョンアップするたびにこの種のトラブルが必ず起こるので困ったものです。
rm -rf /Library/Developer/CommandLineToolsxcode-select --installところで#include_nextはインクルードパスにある別の同名ヘッダファイルを読み込む指示です。インクルードパスは以下のコマンドで確認できます。

今回のトラブルで、私のような非IDE派はCommand Line Toolsさえあればプログラミングできる、つまりXcodeがなくても問題ないということを再確認しました。Xcodeは20GB超えの重量アプリですから、ストレージ不足になったら真っ先に削除するようにします。
