BMW 520i G30 Sunroof Not Opening

I am an owner of a BMW 520i G30 and I am writing due to a malfunction in the sunroof. The sunroof does not open at all and is completely out of use. This problem started today around 12:00 pm and is still continuing in the same way. I have not yet taken the vehicle to any authorized service or dealer, nor have I contacted customer service or any hotline about this issue. However, since this is a functional fault that directly affects the comfort and usability of the vehicle, I expect BMW to support me on this matter. I request that the sunroof malfunction on my BMW 520i G30 be diagnosed as soon as possible and repaired free of charge. I kindly ask you to contact me, arrange an appointment with an authorized service and ensure that this problem is resolved without any cost to me.
