The moon is too close for the Hubble telescope to image as well as being to bright. This naturally is more proof of the “cover up”.
Hubble is designed for imaging things light years away. Even pluto is too close for Hubble to clearly image.
Actually, you are almost right about Earth's Moon being too close and too bright for Hubble. HST was used to study light curve changes
during the Venus Transit, for example.
Below is one from a famous set of 'full moon' shots of the Moon's nearside, specifically of bright Aristarchus and Schröter Valley on the Aristarchus Plateau. The same set includes Hubble's best view of the Taurus Littrow valley, explored by Cernan and Schmitt of the Apollo 17 expedition in December 1972.
