Unity can't open any project

Hello everyone. I've got a problem with unity. I'm useing unity3d 2017.1.1f1 And now it can't open any project (include new, which one was just created). Few hour ago everything was allright. But now, after I choose any project (with project window), nothing happens. Unity.exe is in processes with ~170 mb ram used. And nothing more. I've already tried to reinstall it, to remove AppData\roaming\unity folder, reboot pc. Any ideas, how to fix it?
