Minecraft launcher crashing before showing up after an update.

This problem appeared when i launched the launcher and it downloaded an update after that it started to crash immediately after. The day before the update everything was working perfectly fine.
When i click on the minecraft icon to launch the launcher it crashes before even showing appearing on screen, now i can't launch it by any way any more.
The problem is consistent even after restarting the computer and updating Java to version 8 Update 121.
