Minecraft crashes on launch
Solution 1:
This looks like a Minecraft bug, you should post it on the bug tracker (you'll have to create account for that)
Meanwhile, try to change the JVM locale from the Minecraft launcher:
- Click on 'Installations' at the top
- Click on the the version you are playing (it will probably say 'Latest release')
- Click on 'More options'
- In the 'JVM Arguments' field add
-Duser.language=en-US. Make sure you do not change the other arguments and that what you are adding is separated from them with a space.
If that does not work for some reason, check if you can change your Windows locale to English. This may break other programs on your computer though.
