[MC-247416] Uncaught exception during initial worldgen deadlocks the game

Uncaught exception during initial worldgen (such as MC-247415) will deadlock the game instead of crashing. This also prevents crash reports from being saved properly. Note that this issue only occurs on some seeds.

Steps to reproduce

Trigger MC-247415 or other bugs that crash the game during initial worldgen with the seed -5577097941836652926
Observe that the game does not exit and is stuck during worldgen
If the game exited, try another seed

Expected Behavior

The game should crash on uncaught exceptions.

Are you able to provide a seed for which this happens?

This may be a bug in third-party launchers, but I am not sure whether the responsibility is on the launcher side or the client side. I used the seed -4298465435144430922 in my testing if I remember correctly.

Thanks! I'm unable to reproduce using that seed, but I did reproduce the issue using the official launcher with the seed -5577097941836652926.
