forceDirection.Normalize() alters the forceDirection vector and returns void, rather than returning the normalized vector. So you'll need to split the Normalize() call and the multiplication into separate statements:

Vector2 forceDirection = enemy.transform.position - transform.position;
forceDirection.Normalize();
Vector2 force = forceDirection * thrust;
