Thank god this was already reported much earlier, I was worried i would be having to stay off minecraft for much much longer. Also the fact you basically lose the M1 ability in minecraft after this makes it unplayable since You are unable to kill any mob without throwing tridents.  Also is there any way to undo this bug? 

Yes I did. It still isn't fixed for me yet. I have closed and opened my world and minecraft and the computer on its own, all 3 several times. Hopefully It will work even once so I can atleast use something other than trident ranged attacks to kill mobs
