XCode 14.2
>Description:
Installation fails with a message from `pax` that `File exists` and it's related to the creation of `.` so the directory itself.

>How-To-Repeat:

>Fix:
Instead of copying the installation directory that is already created only copy the files inside the directory and not the original root directory.
