world keeps crashing

ive made 5 survival worlds in the last... who know. now, i stopped playing ONE due to my stupidity of building wood in a plains biome. but the other 4 were COMPLETLY bugged. my 2nd and 3rd had massive chunk errors, my 4th was somehow deleted when i tried playing it but the one i just made keeps crashing. heres the report:
