Nullability of reference types in type of parameter 'type' of 'object? TypeResolver.Resolve(Type type)' doesn't match implicitly implemented member 'object? ITypeResolver.Resolve(Type? type)' (possibly because of nullability attributes).

Cannot convert null literal to non-nullable reference type.

Possible null reference return.

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

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

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

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

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

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
