What is this part ?

Thanks !
So, there is a space between my belt and the snubber (like 1mm ?). It's not good ?

There should be a very small space between the snubber wheel and the Gates belt, so that would be fine
Okay.
I hear a squeaking noise when I pedal fast (in turbo and in medium or easy gear) and I was wondering if it was coming from the snubber...

for the belt. Could be a number of things, when did the bike had is last service? Did you check belt tension? if the noise gone when you hose of the bike and run a quick test run in the given support/gear? (for the last one, could be something rubbing which needs some lube).
I couldn't reproduce the noise with the bike upside down, but I tested it without the motor, and although I could hear the noise less, it was still there.
I heard two fairly loud “clicks” recently, when I was pushing hard on the pedal. I'm going to clean it up and test it again.
The bike was checked 400 kilometers ago (1 month and a half). I don't know about the tension, I'll check with the Gates Carbon app.

One of those
One of those. With "sonic" testers I have the experience that those are not always very secure for bicycle usage, like the cricket tool also not usable.

There is a certain frequency of twang when you tap a belt that is properly tightened. There are gauges for measuring this. Clean the belt with soapy water and rinse well. Then apply a some drops of DOT 5 pure silicone oil. The belt or cog or both could be worn.
It's around 45Hz. I guess it's fine.
I washed the belt but the high-pitched sound remains.

sounds like a plastic part which scraps against a moving metal part. Did you try the water spray test? hose of a certain part of the bike (starting at the hub interface) to hear if that part is quiet with some water-lubricant. in such a way you could find the area where the rubbing is occurring. Also in [sound2] I think I hear a brakepad rubbing to the rotor.
Oh, well. Your diagnostic is pretty impressive ! How can I adjust the brake pad noise ? It's probably too tight.
I only hear the noise I've posted here when I ride, I didn't manage to hear it with the bike upside down.
I've washed the belt and sprayed water in many places, but I can still hear the sound posted above; mainly when the enviolo is halfway down and when I pedal quite strong, by the way.
I think I don't know how to do this. xD
I tightened the cable more but it made my rear brake softer.
But still, you're probably right, you can see the breakpad touching the disk in the first picture, not in the second.
By the way, when the bike is upside down, I can see this part ?Why is this part hollow ? What's the purpose ?

Ok, I did not propose to hose down the belt. For some reason when bikes in the field (either visited by the mobile mechanics or via a dealer) cannot be diagnosed/repaired these bikes in the end arrive at my desk to find and repair the issue in it.
For this type of noise the fastest way to find where it is coming from is to spray water on a suspected area (around the rear hub at the interface, around the crackset etc) and take the bike for a spin. If the noise is gone or sounds different you have the spot where it is coming from and you could fix it.
The steerer tube you show on the last picture is a hollow tube which is pressed into the fork's bridge. Since it is a tube which is formed with a big awl to math the fork's bridge it cannot be solid. Also there are a lot of aftermarket parts which take advantage of this hollow tube. From integrated tool holders to fender mounts.
for example you see one here on a show stand, the steerer tube is cut open so you can see where the tools are
Also the krallenmutter/starnut or expander plug goes in this tube to be able to set the preload on the A-head headset.
and you could also use this one, thought there where long gone but stil there https://miles-wide.com/product/fork-cork/
