I am using 11.6

Weird that is the same as me. (11.6.1)

So the next question is which version of clang do you have?

According to this thread: https://stackoverflow.com/questions/63972113/big-sur-clang-invalid-version-error-due-to-macosx-deployment-target

Your bug seems related to the command line tools installation and maybe to the an environment variable
SYSTEM_VERSION_COMPAT

In my case, I have this version of clang
$> clang --version
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

and did not set that environment variable
$> echo $SYSTEM_VERSION_COMPAT
[no returned value]

That thread claims that my clang version is problematic, but I do not have that issue....
but i would advise to follow the instruction in that thread and reinstall command line tools

Cheers,

Olivier

So this helped to solve the problem, thank you very much.

The problem was an non compatibility between the macos version and the xcode version.
The solution steps are :

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

And then the run is working succesfully

Cheers :)
