Disconnected due to an unexpected type of packet received which cannot be processed.

When I was creating a new world to play with cheats on, it gave me an error saying "Disconnected due to an unexpected type of packet received which cannot be processed. This could be due to a version mismatch or corruption at the networking
level." Please fix this bug as soon as possible. And there is a screenshot attached below.

 

Things I did when I was creating my world-

1. I kept the gamemode to creative
2. I kept the difficulty to peaceful
3. I kept the seed to default [to generate into a random world]
4. I disabled TNT explodes
5. I enabled keep inventory.

Then clicked on create which showed this error.

Thank you.
