Hello

I have a problem with my minecraft account.. 

I cant launch the game, i watch every video on youtube every solution to that problem but nothing helps. when i press on "Play" the game crushed with one message "An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience."

I add "launcher_log.txt" 

 
violine1101 said that -Xss1M This Java argument is causing the crash.
And ask to Reset the JVM arguments in the "Installations" tab. And i cant reset it... only if i delete something from that JVM argument its give me the possibility to reset it to the same argument.  I did it but that didnt work the game still crash.
