I found a glitch when you equip "Chameleon Raider right arm" It's a right arm armor piece that increases sneak and makes you invisible while standing still while crouched. However, when crouched and invisible, accessing the pip boy glitches it out to where you cannot navigate it at all. It's very bright and the menu is enlarged and sometimes the menu itself is invisible too. The world itself also brightens quite a bit when crouched sitting still. Pretty bad bug. Just thought I'd let you guys know! Fantastic game.
