[MC-156111] Game crashed because of an entity colliding with a block (1.14.3)

I was in The End mining cobblestone and netherrack I had placed around the portal, then my game crashed. Now when i try to load the world, the game instantly crashes. I should probably add that before I was mining the cobblestone and netherrack, I was adventuring the end midlands/highlands for end cities and I went out about ~20,000 blocks. I should ALSO mention that this is currently keeping my world hostage.

EDIT: SO I FIXED IT ))) what i needed to do was paste /kill @e[type=item] into chat to clear the item that was stuck in the block. you couldn't believe how relieved i am right now.
