Xcode 11.3 crashes on launch in macOS Catalina 10.15

Question

I've updated my mac to Catalina 10.15 so I can install and work with the latest Xcode version. After installing the software from the App Store, when I click to start it, but it crashes and shows this error message:

Loading a plug-in failed: The plug-in or one of its prerequisite plug-ins may be missing or damaged and may need to be reinstalled.

I checked the console and I found:

Legacy client com.apple.dt.Xcode connecting to modern client. You can't mix modern clients with legacy clients. ClientConnect: 0x00007fedb3577170 identifier: com.apple.dt.Xcode pid: 773 type: Application>

And the System.log says:

Dec 20 00:38:08 MacBook-Pro com.apple.xpc.launchd[1] (com.apple.xpc.launchd.domain.pid.Xcode.837): Failed to bootstrap path: path = /Applications/Xcode.app/Contents/XPCServices/com.apple.dt.Xcode.SymbolicateXPCService.xpc, error = 129: The service was superseded by a later version Dec 20 00:38:09 MacBook-Pro com.apple.xpc.launchd[1] (com.apple.AMPDeviceDiscoveryAgent): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

Can you please tell me what's wrong? and how to solve that so I can run Xcode on my Mac?

Try to set the date of your Mac as October 1st, 2019.

After components has been installed, change the date to current again.
