Fixes #19843
This fixes an Internal Error where namespace packages were not supported properly. We have to use
os.path.isdir(tree.path)instead of trying to catch anIsADirectoryErrorexception because of a bug on Windows which causes it to throw aPermissionErrorinstead in the relevant situation, which makesexcept IsADirectoryErrorunreliable. (We also can't justexcept (IsADirectoryError, PermissionError)because what if there is an actual permission error?)
