Hello!
Recently while playing 1.16 Pre-release 2, I came across a bug that prevented me from interacting with the world. I.E Could not eat, attack, shield, etc...

I was able to produce the bug by moving in a boat and leaving the boat while moving. This also applies to being forcefully kicked out of the boat when the boat breaks.
It seems to keep the same effect as moving in a boat where you cannot interact or see your hand etc...

Hope this report helps
