Cant start the game

Anytime I try to install the minecraft launcher on my computer, it installs perfectly fine, but when I start it I login. Then I get "Woops! Something went terribly wrong and you probably encountered a bug. Please file a report."Below there is a "try again" - button, that doesnt do anything. Restarting the game doesnt help. Reinstalling the game doesnt help.  Restarting the OS doesnt help. Reinstalling the OS doesnt help

 

Suddenly after writing this I just started Minecraft and it started and let my play the game as normal. I have no idead what fixed it. I was really frustrated ans suddenly it decided to be generous.
