While I was searching for some clay in my boat, I exited quickly out of the boat while my hand weren't showing, and they weren't on my screen. Went to go dig the clay and it was fine but tools weren't showing up and found out that I couldn't get back inside my boat or open and doors. Went in third person and my tools were still in my hand, just not visible in first person. I have provided you with a video for you to check out how I did it. Hoping this gets fixed soon and I can safely exit my boat swiftly and not have to exit and rejoin my world.  I am not aware of this happening in Bedrock edition.
