"xcodebuild -version" reports double defined symbols

I upgraded to Xcode 13.3, Build version 13E113, in order to work around issues I found with Xcode 12. In both Xcode versions I get a number of warnings or errors on launching xcodebuild. I reinstalled the command line tools but the messages don't go away. Here is the print out, does anyone have the same issue?

xcodebuild -version

Xcode 13.3

It happens from time to time, some duplication in Libraries.

You don't have to worry and can usually safely ignore those warnings.

seeing this too on a M1 Monterey, when run xcodebuild clean or archive, it just happened several days ago, might be after a homebrew update or something.

xcodebuild clean : stuck there with the error msg as abovexcodebuild archive: exit immediately after the error msg as above
