I logged out of a world while falling and when I tried to quickly rejoin I was repeatedly pressing right click (in bursts) to block any remaining fall damage but somehow triggered an infinite loop of "Loading World" and "Generating Terrain". This started 30-45 minutes before posting this and has subsequently caused the game to freeze and forced me to close the game with task manager. It might be worth noting that the game launched with an error already reported in [MCL-1905].

Before anyone asks me to manually trigger a crash just know that I've tried, and failed, to do so by means of F3+C.
Attached is the log from this event.
The log is too big to be attached so a GZip-ed version is attached instead.
