Havent been able to play for a year

We have not been able to play for over a year now. The game loads to 100% and then says saving world and crashes. It has always been this same error.

I have reinstalled Minecrafted.

Uninstalled and Reinstalled Java.

Removed all antivirus and malware scanners (which isn't that smart to do just for minecraft)

Currently the game still gives the exact same error. 

 

I have looked at MC-34749 which your answers repeatedly state has fixed the issue, And it DOES NOT fix the issue.
