I was running a server on 1.16.4 and when I tried to start it up today it had automatically set to 1.17.1 and when I tried to change it only 1.16.5 was available. Once I changed it to that and installed a version I was then unable to join the server and was instead sent to the minehut hub. Please help, I'm unsure whether the world is corrupted but it is currently unplayable.
