End gateway portal teleported into a black space; unable to load game now

while in the End, used Ender pearl into end gateway portal, upon teleporting it took me to a complete dark place, coordinates I believe were 176, 60, 0, I know for sure the Z cord was zero. I tried to move, mine, jump, never took damage either. I sat there for approx. ten minutes. when I came back I tried to quit the game it would not let me quit. I then tried returning to the game it loads to the last green bar when initializing game. Then I closed the program completely attempted to load same saved game, not able to finish initializing still, restarted computer and still same issue. This is my first time reporting an issues, I have searched for any possible solutions and keep getting informed to report the issue. I tried to attach export of game after issue happened. However, it is 267.66 MB and exceeds. Other saves work though.
