[MC-37463] Hopper: java.lang.NullPointerException: Initializing game @ azd.a(SourceFile:502) // setDisplayIcon

Possible solution

This bug is very likely caused by one or two corrupted asset files:

icons/icon_16x16.png
icons/icon_32x32.png

Solution (1.11.x and 1.12.x)

This is the solution which should work for 1.11.x and 1.12.x. This may also work for other versions. For a general way to solve this, see "Solution (general)".

Delete the following files and try to start Minecraft again.

.minecraft\objects\bd\bdf48ef6b5d0d23bbb02e17d04865216179f510a
.minecraft\objects\92\92750c5f93c312ba9ab413d546f32190c56d6f1f

Solution (general)

To solve this problem you have to do the following:

Open the index file in the .minecraft\assets\indexes folder of the version which you are trying to play. The file is a normal text file and can be opened with for example Notepad++. The file has probably a name like 1.11.json (for 1.11)
Search for the two file names listed above
For each file name do the following:
1. Remember the hash value
2. Open the .minecraft\assets\objects folder
3. Open the folder whose name is the first two letters of the hash value
4. Delete the file with the hash value as name
Try to start Minecraft again

This issue popped up for me just yesterday, interestingly it's occurring on both my WinXP desktop and on a Fedora/Gnome desktop. Quite reproduceable, as in the game never starts. However, the launcher continued to work fine at another location on a Mac and a PC. May get around to trying more thorough testing today, e.g. remove .minecraft folder and re-install.

OpenGL: ~~ERROR~~ RuntimeException: No OpenGL context found in the current thread.

This states that your current video card driver doesn't support Open GL. Please update your drivers if you get this issue.

hydra_2_1 2013-12-08T18:25:02Z

I have tried this solution, it does not work

Zach M 2013-12-29T18:53:57Z

Yeah, that solution doesn't work... My video card/Graphics card drivers are fully updated....

galaxy_2alex 2013-12-29T18:58:00Z

If you have the exact same error, try remove the JVM Arguments.

Has anyone having this issue a modified desktop (inofficial skin) ?

Ciara Camp 2013-12-30T16:45:20Z

@Kumasasa Yes I have an Alienware theme modified desktop.

Tracy Joy 2013-12-30T19:34:49Z

Is it just me being stupid, or is there no way of getting any simple guidance on how to resolve this without needing a degree in computer programming - any guidance would be appreciated. I have bought a brand new laptop, the technicians have checked the laptop and tell me the issue is with Minecraft and to escalate with them, which I thought I had done but I am absolutely no further forward.

kumasasa 2013-12-30T20:59:00Z

@Ciara Camp: Does the crash still occur, if you switch off (uninstall ?) the desktop theme ?

kumasasa 2013-12-30T20:59:28Z

@Tracy Joy: There is currently no solution for this issue.

Tracy Joy 2013-12-30T21:48:01Z

Why does your reply - not just say that ? So are you going to refund the monies that I paid up you ? Thanks

We cannot refund your money, however you may email support here

Tracy Joy 2013-12-30T22:08:02Z

I will be reporting this as a fraudulent debit from my account, you have told me that you are unable to fix the problem and yet you will not refund my monies - how can you justify that ? !!!!!!

Tracy Joy 2013-12-30T22:12:06Z

And the link you have sent me does not work - this is a complete joke !!!!!!

It works for me, try going directly to http://help.mojang.com/customer/portal/emails/new

We are not Mojang, we are volunteer's who organize the bug reports and crashes. We cannot refund you money, you must contact Mojang support

Tracy Joy 2013-12-30T22:24:05Z

Apologies I thought u were Mojang - sick to death of it all!! Apologies again !!

Alright so, if your crash report has this in the crash report at
azd.a(SourceFile:502)
at azd.Z(SourceFile:340)
at azd.e(SourceFile:689)
at net.minecraft.client.main.Main.main(SourceFile:103)
you fix it by uninstalling your minecraft and reinstalling it, (im not sure why it does it in the first place but on my schools network its blocked but i uninstalled and reinstalled it on a diff network it worked again) P.S this fix is guaranteed ONLY if the source files match up, if not I can not be sure if it will work for you

Zach McDaniel 2015-03-30T20:06:36Z

Uninstalling did not work for i cannot get in.

kumasasa 2016-05-08T02:33:32Z

~~No longer an issue with 1.9.2~~

bob 2016-11-06T11:10:50Z

Is this still an issue in the latest snapshot 16w44a? If so please update the affected versions.

This is an automated comment on any open or reopened issue with out-of-date affected versions.

marcono1234 2016-12-13T21:48:16Z

Added 1.11 as affected version because of MC-111347

marcono1234 2016-12-13T22:06:41Z

@@unknown this is very likely not a OpenGL problem. If I modify the assets in a way that they create the exact same report all OpenGL data in the crash report is empty as well. But without modifying the assets I can play Minecraft just fine.

Barbara Vos 2017-03-13T18:08:16Z

Oke, tried this yesterday. Didn't work!
Still can not launch Minecraft in any version, with any launcher.
Please fix this - even better, roll back this great new launcher, that is causing so much problems for so many people!

marcono1234 2017-03-14T14:59:48Z

@unknown please try the provided workaround (big yellow box) and see if it solves your problem

Barbara Vos 2017-03-15T14:39:58Z

Like I said: I already tried that and it doesn't solve the problem.
Besides that, on the other two pc's in my house, those of my sons, with their own, completely different configuration as mine, Minecraft can also not be started since the introduction of your socalled improved launcher!
Furthermore I have heard from 3 different friends that they have the same problem.
So you see, this problem is not ours to fix, it is Mojangs' to fix, so please fix it as soon as possible!

marcono1234 2017-03-15T22:04:54Z

You can follow these steps to get the old launcher while this issue remains with the new launcher.

Andrew Bres 2017-06-23T17:12:15Z

This did not work for me.
Here is my crash report :

Jaidan Hanshaw 2017-09-02T17:29:23Z

This did not help me. I deleted the 92750 file and the bdf file, but it still crashed. The only thing I can think of is that Minecraft Forge is broken or something.

It keeps saying, "The game crashed whilst initializing game. Error: java.lang.NullPointerException: Initializing game", and it won't let me view the crash report.

Roger Hanson 2017-10-09T08:17:46Z

I had to litterally go into my Minecraft File and take out my saves. After I did that I backed out of the Minecraft file and deleted. I didn't delete the launcher, instead, I opened the launcher and allowed it to create a new minecraft folder. I took the old minecraft folder out of the recycling bin and put it on my desktop. I then deleted the new saves folder from the new minecraft folder and placed the old saves folder inside of it. The first time I tried to open the launcher it froze too, but I just backed out and tried it agian and it worked. It works now, but I can no longer use the old versions. I have my save worlds, though, so I guess that is alright. I really did like 1.8 and 1.10, though, so that sucks.

Uriel Salischiker 2018-10-02T20:24:03Z

Is this still a issue in the latest version of the game(currently 1.13.1)?

If so, please add it to the affected versions, thanks!
