Player Model doesn't show up in inventory.

When I open my inventory or go on the pause screen in any world (even if there are no resource packs or behavior packs on) I can’t see my player model in the top left of my inventory or the pause screen. It’s just a blank, black screen in my inventory, and on the pause screen the player is just gone. I tested it on multiple worlds, and I don’t have invisibility on so I don’t know any other reason for it other than a bug. My player is still there in game, just not on any menu. Even closing minecraft and re-opening it doesn’t fix the issue.
