When i try to open minecraft 18w01a, it opens the loading screen for a sec and then it crashes. The crash error is this one:
The game crashed whilst initializing game
Error: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Unterminated object at line 4 column 59 path $.pack.description
The minecraft game output is this one (without showing the debug part):

I'm not using any texturepacks or mods or anything, just vanilla. As i've tried running without any other programs working at the same time. I've disabled the texturepack i normally use from minecraft 1.12 client and the snapshot still not works.

I've read that issue, and i'm not using any texturepacks while running the game. I've disabled the texturepack i normally use from minecraft 1.12 client and still not works.

Try removing the resource pack entirely by placing it in a different folder. Minecraft still has to read the contents of a resource pack in order to generate the resource pack list, thus causing the crash regardless of whether the pack is enabled or not.

OMG, it worked! Thank you so much Zero318 😃
