Run "osascript -e 'do shell script "xcode-select -switch /Applications/Xcode.app" with administrator privileges'" to configure Xcode. You must be an administrator of this computer to complete this action.

Do you happen to share network drive with a Mac, or did you happen to copy your files over from a Mac?

XCode is a compiler for MacOS. If you run Windows 10, this message should not appear. As Walter asked already: Did you copy files in the prefdir folder from a MacOS installation? But even then modern Matlab version look for a file like "mex_C_win64.xml" and a collision with another preferences file is unlikely.
You can try to re-create the preferences files. Rename (not delete) the preferences folder and try, if the automatic re-creation and a new mex -setup solves the problem. Then you can copy the newly created compiler setup file to the original folder and restore the former preferences folder.
If this does not help, try:
mex -v -setup
and post the results here.

I am experiencing a similar problem when trying to run the mex setup. This is the result from the mex -v -setup
>> mex -v -setup -c
Verbose mode is on.
... Looking for compiler 'Xcode with Clang' ...
... Looking for environment variable 'DEVELOPER_DIR' ...No.
... Executing command 'xcode-select -print-path' ...No.
Did not find installed compiler 'Xcode with Clang'.
Warning: Xcode appears to be installed, but it has not been configured. Run "osascript -e 'do
shell script "xcode-select -switch /Applications/Xcode.app" with administrator privileges'" to
configure Xcode. You must be an administrator of this computer to complete this action.

In MATLAB, command
!osascript -e 'do shell script "xcode-select -switch /Applications/Xcode.app" with administrator privileges'
Also, make sure that you start up XCode once, as it is necessary to agree to the XCode license before you can use XCode from MATLAB.
