OMG why cant i play minecraft in peace

for the past maybe 8 months or so, my bedrock has been so weird to me. at first when this happened i didnt give it much thought, and just turned off my console and hopped on my 360 instead. but later this started happening more regularly and now minecraft isnt even playable for me. i know it has nothing to do with storage since i have ALOT of space left. I havent downloaded any stuff onto my xbox one s. i really dont know whats the cause of this. ive restarted the game, restarted my xbox, gave it time to load and... nothing. literally just now when i was in this corrupt ass world it QUIT BY ITSELF and crashed my entire game. 

i attached some images to show what i mean by corrupt cuz this is really weird (soz for my dirty camera i wasnt bothered to wipe it lol) i also have had times where i'd be in the menu and when i pressed play, it would just take me back to the menu screen (if that makes sense). im mostly just posting this just to rant, cuz i do have a lot of old minecraft worlds on here that i really dont want to lose to this random bug and i really just want to play some minecraft, but if anyone has experienced this issue and/or knows how to solve it pllzlzlzlzllzlz tell me.
