After waiting for the pre-existing world to render/load for the first time (during which time it was all air blocks except for clouds), the game crashes to the launcher. The issue is repeatable, the crash occurs nearly immediately (before any game input can be accepted, i.e moving or looking around) after opening the world and seeing the game. I have 0 (zero) mods installed.

Crash report timestamped at 15.25.46 is the first crash (which occurred after the world was loaded in and chunks were finished rendering)

Crash report timestamped at 15.27.13 is the issue being repeated.
