Using std::filesystem::exists(std::filesystem::path) does not catch operating system level errors

[imikejackson]

That method can throw exceptions from the operating system level. All uses of this signature should be replaced with the 2 argument signature and appropriate code changes to effectively now use that signature. https://en.cppreference.com/w/cpp/filesystem/exists

The 2 argument does not throw an exception but instead encodes the underlying operating system error into teh "std::error_code" object.
