This is weird, I also get this problem, but actually AppStore said, it is already updated to Xcode 14.2
Still I get that error message: "You can't open the program Xcode because it is updating".
I still use macOS Monterey 12.6.1

I tried to run Xcode from command line (Xcode/Contents/MacOS/Xcode) and it works fine.
So I deinstall and reinstall Xcode 14.2 and afterwards it works just fine.
