MacOS 12.x (Monterey) disables the Xcode 12.5 app

Updated to MacOS Monetary (12.0.1) yesterday.

After the update, the installed version of Xcode (12.5) was marked as disabled. Attempting to launch Xcode displayed the message:

"The version of Xcode installed on this Mac is not compatible with macOS Monterey.”

LC 9.6.5 (rc 2) launches and appears to function as before. Despite the Xcode app being disabled by MacOS, LC Preferences > Mobile Support shows that the iOS 14.5 SDK and simulators are still recognized. I was able to compile an iOS app and also run an iOS app in the Code 12.5 iOS simulator.

I was also able to compile and run a MacOS app.

So it appears that launching the Xcode 12.5 app (and earlier versions presumably) is not supported by MacOS 12.x but LC can continue to use the iOS 14.5 SDK and simulators. A Mac App compiled and worked as expected (have not tested this MacOS app extensively).

I use the Xcode app for other work. Are there plans for LC to update to Xcode 13? 

Can I have two versions of Xcode installed (12.5 and 13.x) and use the 12.5 version for LC and 13.x as the standalone Xcode app? Will installing Xcode 13.x overwrite the 14.5 SDK and Simulators supported by LC - even if I rename the 12.5 version of Xcode to “Xcode 12.5” and then install Xcode 13.x as the default Xcode app?
