I've had this happen several times. During each occurrence, I would be immobile during the first (blank terrain) phase, then regain movement during the second (purple & black) phase. After the second phase the terrain would appear normal again but I'd be completely invisible - including equipped armor and off-hand item - in third-person view. In first-person, the main hand and equipped item was invisible, but other hotbar items visible. I have waited up to five minutes with no change, eventually saved and exited each time. Returned to normal after logging on again. (Nintendo Switch)
