What could cause a large blank area with no stars around the moon? Stars appeared as normal beyond this circle?

"the moon is so bright that your eyes cannot adapt to see both it and the relatively dim stars that are around it in the sky"
Harvey is correct.
I would think this would be an optical illusion caused by the brightness of the Full Moon. When viewed through a telescope, you can see stars right up to the limb of the Moon.
There were too many lights around where you were. The other stars could be too far back as well.
I’m guessing here, but…
I think you might have seen high-altitude suspended ice particles in the atmosphere through which the moon was shining. Because this ice was scattering the moonlight, it was too bright in the immediate vicinity of the moon to see the much dimmer stars in the background. After you get out far enough from the moon, the refractive angle of the ice is such that any refracted moonlight is diverted away from your eyes, allowing the stars to be seen. Just a guess, but I think it was something like that.
