[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
