Xcode 12 GM Seed doesn't start - 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 am running on DTK Big Sur Version 11.0 Beta (20A5299w)

From Beta downloads page of Xcode 12 GM Seed 1:

Xcode 12 includes everything you need to create amazing apps for all Apple platforms. Includes the latest SDKs for iOS, watchOS, and tvOS, and macOS Catalina. For development on macOS Big Sur or to support Apple silicon, continue to use Xcode 12 beta 6.


FYI:

From Console app:

Error reading receipt: Error Domain=NSCocoaErrorDomain Code=260 "The file “receipt” couldn’t be opened because there is no such file."
