Ignoring paths does not work like that

These lines are not necessary and also wrong.

The Finder internally evaluates if we want to ignore VCS paths and adds the paths to ignore here: https://github.com/symfony/finder/blob/v4.4.4/Finder.php#L702

If you loop through the files, you are ignoring basically EVERYTHING and that by accident, too.
This is because you are passing a file object to the Finder::notPath() method, which gets converted to an array. The conversion works, but the output is not what Finder::notPath() excepts.

So basically you are ignoring random paths.

Just remove the loop completely and you should be good to go ;)
