The bug
After doing certain actions, the shield blocking animation is not displayed. If you right-click, you will see that the shield bobs up and down, indicating that the player is currently blocking with the shield. This also affects the loading animation for bows and crossbows (which the crossbow does not bob down to go in the middle), as well as the fishing rod's cast texture, and does not affect the third person camera modes.
This bug is known to happen after the following actions:
Getting killed and respawning
Quitting to title and rejoining the world
Changing dimension
Using a water bucket
Equipping armor
Opening a container's inventory
Interacting with a villager or wandering trader
Switching to another hotbar slot
(List may be incomplete)
The bug no longer happens as soon as the affected item's inventory slot is updated.

Not to mention if you have a loaded crossbow in your off hand and another item in your main hand, the crossbow will completely disappear in First Person View.
i am on snapshot 20w12a, and i keep having the shield become unusable until i unequipped and reequip the shield, the quickest way is tapping F twice to move it to main hand then back to offhand, i notice it happening the quickest/most frequent during building/digging projects (i have been changing hotbar slots with mouse wheel and click and dragging tools to combine repair them and make new tools at the crafting bench and accessing furnaces and chests and digging and placing blocks, basically digging/building an underground base underground using stone bricks, seems to occur once every 2-10 minutes doing the above actions).
