Nobody until Robert has ever given me this easy set up for shooting the moon.

It is normal for a camera to overexpose a lighter subject on a dark background. The exposure meter is attempting to have the dark background show as 18% Neutral grey. So more light is allowed in to brighten the large dark area, and as a result that also lightens (overexposed) your small brighter subject. The same thing happens when shooting pics or video at a nighttime concert.
With this example, you have obviously realized the need to underexpose from the cameras meter reading. That is accomplished by minus exposure compensation, or with the moon it is often easier just to manually set your aperture/shutter speed/iso. This is one of those situations, where you simply cannot let the camera determine the correct exposure for you. It doesn’t have the ability.
Having the knowledge that the moon is roughly the same exposure as midday on earth - in Manual Exposure Mode I can work from a starting point of something like f11 @ 1/500’th @ 400ISO (Sunny16 rule would be f16@1/400’th@400ISO), and then leaving the Aperture at f11, take several exposure variations by adjusting the shutter speed, until the moon shows detail on the camera screen.
So I did take some shots last night and was very happy.
Both images are right out of my camera with no editing.
