World (Possibly) Corrupted, HELP!?

While finalizing my ship https://www.planetminecraft.com/project ... l-3997563/ , I experienced a lag spike, which took unusually long to respond, and froze my computer in the process. I forcefully restarted my computer (Via turning off power, then on again). I opened the world, however in the loading screen, it was taking unusually long (More than 10 minutes), to open my world. Since I am running Ubuntu, I "xkill"ed minecraft (This is force quit for you windows users). Now any time I try opening the world, the game crashes, presenting a very unusual crash report. Any help/ fixes will be appreciated.

Crash report, incase needed:
