When I was playing my Minecraft world I've worked for years on I went into spectator mode but got lossed so like I usually did I used /kill to get back to my spawn but then the kill sound worked but I was still alive and I couldn't switch back I then tried using /kill again thinking it would work but it didn't so then I left the game and atempted to join my game but it would keep freezing every time so I came asking y'all to give your assistance to get my world back
