I don't think there is a conspiracy against Real Madrid. Because the decisions were the right ones. On the contrary, there are many people who think that Real Madrid made the decision in their favor. Mbappé's absence will make it very difficult for Real Madrid in a difficult match. However, this mistake is Mbappé's. Because he tackled the Alaves player very harshly. He deserved a direct red card. Ancelotti should warn him about this. If Real Madrid hadn't scored, the match could have ended in a draw.
Yes, Real Madrid and Mbappe have also apologized for the foul and they accepted the sanctions for the mistake in the game. There is no other intention, indeed, Mbappe was somewhat provoked by a series of things that made him do it. But the point is, as explained by Davide Ancelotti about this Mbappe red card
