Problem with twitch app

There was some time I didn’t launch twitch desktop app and when i tried to launch it today nothing happened. There weren’t any windows or else. I could see twitch.exe task in task manager but it disappears after a minute. And re-installation doesn’t help. How can I get an app launched?
P.S. realy don’t know where to ask, so tried to ask there
P.P.S sorry for my english
