I have been playing in a singleplayer, legitimate survival world for almost a year and a half now without cheats enabled. I have unlocked the majority of my achievements within this world including some of the new 1.18 achievements today! 

I'm telling you this to prove my world is very much eligible for completing achievements within despite my incapability to complete Super Sonic. Over the past year I have followed countless tutorials, instructions from forums and now even Mojang's troubleshoot instructions and yet I still cannot unlock this achievement.

As of today it is now the only achievement I need to 100% the game which is rather frustrating.

I have seen other posts in this forum regarding the same issue left unresolved and I hope that my post will not suffer the same fate.

Mojang, please fix Super Sonic. I have tried everything, it is clearly not a fault on my side.
