Download Xcode 14.3.1 via this link (you need to be signed in with your Apple Id) and install it
Edit Xcode.app/Contents/Info.plist and change the Minimum System Version to 12
(Optional) Do the same for Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/Info.plist (might require a restart of Xcode and/or Mac OS to make it open the simulator on run)
(Optional) Replace Xcode.app/Contents/Developer/usr/bin/xcodebuild with the one from 14.2 (or another version you have currently installed, such as 14.0).
(Optional) Execute sudo xattr -cr /Applications/Xcode.app if Error "Xcode is corrupted and cannot be opened"
If there are problems with the simulator, reboot your Mac
