Cannot convert null literal to non-nullable reference type.

'PocketCoreUpdater.Divide()' hides inherited member 'Base.Divide()'. Use the new keyword if hiding was intended.

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

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

Non-nullable property 'instance' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'data_slots' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Possible null reference return.

Non-nullable property 'instance' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'id' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.
