Minecraft Forums

So my Minecraft crashes on World Launch. I go into game, click Single (or Multi) Player, then go click Create a World, etc. When I hit Create World, it starts to generate, then the last thing I see is "Loading World, Building Terrain." I've tried deleting .minecraft folder, turning of VBOs, and I don't know what else to do. Also, I'm using Java 32-bit, I think. I can't install 64-bit with Chrome. Another bit of info is that I installed using the .msi file.
I am on Windows 10, 64-bit. Have had no problems until recently.
Here is the crashlog-

(EDIT: added Java type, installer type, and Windows type)

What antivirus you have?

Malwarebyte's Anti-Malware.

Perhaps try uninstalling and reinstalling Minecraft? I don't think simply deleting .minecraft works.

Can you makie a hjt report? Trend Micro HijackThis is a utility that is used to collect diagnostic reports of your computer to help narrow down an issue you may be having. Download: https://sourceforge.net/projects/hjt/files/2.0.5 beta/HijackThis.exe/download Run the program, choose "I accept", then "Do a scan and save a log file". After a while a text file will open. Copy everything, put the log on http://paste.ubuntu.com and give us the link.

That does work

Delete Java with Java Uninstall Tool, then download 64-bit Java 8 Update 111.

java.lang.IllegalStateException: failed to create a child event loop errors are caused by something blocking minecraft, like a antivirus...

I tried uninstalling and reinstalling and the new Java version. Still doesn't work. Here's the HJT Ubuntu link:

CovenantEyes is known to cause issues

If you are using the Covenant Eyes software. Log into your Covenant Eyes account here: https://covenanteyes.com/myaccount/login and go to the Downloads section, make sure you download and use version 7.2.0 or newer.

If you have a much older version of Covenant Eyes(4.5.3 or older), uninstall Covenant Eyes and then install it again with the most recent version.

Also, tell your parents to allow Minecraft through the software, they should allow java.exe, minecraft.exe, authserver.mojang.com and sessionserver.mojang.com

So... my Malwarebytes could be blocking it?
Because the game does launch and I do get to go through world creation, it just crashes after it creates the world.

I'm using 7.2.22. Also, Covenant Eyes has never shown me any problems in the past.

It has been giving problems recently, make sure java.exe and Minecraft.exe are allowed through it, same as authserver.mojang.com and sessionserver.mojang.com (or just *.mojang.com)

Not sure how to let them through- mind giving me a walkthrough?
