My Minecraft launcher wouldn't open. (This was on a Windows 10 HP Notebook) When I clicked on it nothing would happen, I tried uninstalling the launcher and reinstalling it many times but the same issue occurred. When I tried it on another computer also Windows 10, the launcher opened but the message "Something went terribly wrong and you probably encountered a bug."
