Version: 14w26a

Note: The "Affects Version" is not true. I made it not like that because it wont let me select version "snapshot 14w26a" or "14w26a".

I tried to make a Debug Mode World in it but it just crashed my game.

Tried again and again, still crashing

Exit Code:-1

How to get to 14w26a

Open the Old or New Minecraft launcher.

Then go to Installations on Minecraft Java Edition.

Select snapshot 14w26a, or enter in "snapshot 14w26a" in Versions.

Create it.

How to get to where I'm at

Create New World, Then go to World Type.

Hold down Shift while clicking World Type

Keep doing shift>world type until you get to Debug Mode.

Create New World

Join the world.

Expected Results

Game Crashes, and leaves a Report File (Even I don't know what it is)

It should say "Exit Code: -1"

Conclusion of this report

It will crash whenever you attempt to join the world. Therefore, you might have to delete it. I'm kinda feeling like it's a lost cause.
