Nullability of reference types in type of parameter 'x' of 'int NaturalStringComparer.Compare(string x, string y)' doesn't match implicitly implemented member 'int IComparer<string>.Compare(string? x, string? y)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'y' of 'int NaturalStringComparer.Compare(string x, string y)' doesn't match implicitly implemented member 'int IComparer<string>.Compare(string? x, string? y)' (possibly because of nullability attributes).
