It sounds like you are describing alopecia areata of the beard. This is a

Skin color - patchy. It happens on the scalp and other body parts too. Cause is unknown, but generally is not associated woth internal problems. In most cases, the hair grows back in by itself after a few months, though it may recur. Treatments are not too helpful. The association with shaving is, I believe, a coincidence.
I suggest you see a doctor to confirm this diagnosis. Meantime, shave as close as you can so you look normal.
Best.
