I entered the end islands and located an endcity but before I could get close, the game would crash, I tried it 3 times and every time it crashed at the same point. Crash report says its to do with loading the chunks. Found another much smaller city 1000+ blocks away and it was fine, come back to the one very close to my spawn and it crashed.
seed, crash report and F3 screen are present in attachment files, hope that helps
