I don't know what caused this issue, but it has happened a couple times to me now. I select a certain piece of clothing (I think it might be the "Witch's Robe" in the "Outerwear" menu) and Minecraft lags a bit, then produces this message on the screen: "[Animation][error]-minecraft:player.0.persona-8b9bec571fbe08d0-41b99b77c-3caa-4aaa-8f79-f79f053e586f | Animation component's bone orientation missing expected skeletal hierarchy index!?" and it repeats that message 4 times from the top of the screen to around about the middle.
