Nullability of reference types in type of parameter 'other' doesn't match implemented member 'bool IEquatable<AbiMethod>.Equals(AbiMethod? other)' (possibly because of nullability attributes).

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).

Possible null reference argument for parameter 'path1' in 'string Path.Combine(string path1, string path2)'.
