Greetings! So, I've been experiencing this issue since the 1.14 version of Minecraft Bedrock. 

• So, here's the bug I have encountered during gameplay: This mostly happens when I play locally with someone else besides me. Whenever we play, I mess around and kill my friend in the world we created. After they respawn, something looks off. My friend's player model goes stiff and no animations to be seen and is now set in stone until we quit and go back into the game. A similar bug happens, but instead of going stiff, they get stuck in the crossbow/bow pulling animation and they stay like that as well. I hope this can be fixed.
