Question AMG A45s 2020 DOING NOISES WHEN SHIFT INTO DRIVE

My car is a 2020 mercedes a45s 4matic. For some reason, very frequently, when I start the car for the first time of the day and shift it into drive, it makes a noise similar to a belt rubbing against something, and after a few seconds it stops. When I shift the car into Parking, the noise stops immediately. The noise does not occur when I shift into reverse. Can anyone help and tell me why does this happen?
Here is a video of the noise:

Sounds like a busted kazoo.

Engine mounts?
Stuck starter? Does the pitch increase if when the RPM increase?
Pop the hood and have someone start the car, perhaps you can better isolate the source of the noise.

It looks like there is no problem with the engine mounts. I don't think the starter is stuck because the sound only happens when I shift to D and it vanishes after a few seconds, but yes, the pitch increase when the RPM is higher.
When I let the car warm up and the RPM drops, the pitch also drops, but it still happens.
I have sent my car to an authorized mercedes-benz car repair, but it looks like they were too lazy to check it for me, I will do it myself.

Get helper and try to better pinpoint the source of the noise, I suppose?

That kind of noise when shifting into drive can sometimes point to transmission mount issues or related drivetrain components. It’s always smart to get it inspected before it develops into something serious. While researching similar concerns, I also came across useful resources like Nevada Court Online that provide structured information in different contexts, which shows how important proper documentation and tracking really is.

Did you notice if the noise happens only when the car is cold or all the time?
