ZOMG! I am an idiot and did not backup my game!
Well, sad times. There are some options you can try here, but they all will require expertise in Minecraft files.

Try looking at the crash log in logs/latest.log and see what may be causing the issue.

Corrupt chunk
If the crash file identifies the corrupt chunk or Region file (each Region file is 16x16 chunks), then you can try these steps - First, backup your level.dat and level.dat_old files. - Delete level.dat and rename level.dat_old -> level.dat - If this works, great! If not, continue... - Copy the whole save folder to create backup. Also save off your Journeymap and tcnodefinder directories now too. - Go through the .mca files in the save dir and delete them one by one to find out which region file is corrupted. If you have an idea which chunk might be causing it, you can look at the pictures in the Journeymap directory to see which region file it may be. The names of the pictures in the Journeymap directory correspond to the region. - Once you know the corrupt .mca file, you can decide to delete or repair it. If the Journeymap for that chunk shows nothing important, it's ok to delete. Minecraft will regenerate the chunks fresh next time you login. - If you need to repair (chunk with base or whatever) use a map editor / NBT editor to import the mca file and edit just the bad block or entities.
