I’ve got the same issue friend. I verified the files through Epic Game Launcher and all is okay, but when I’m searching for a match of any kind, the game crash to the desktop. Until yesterday I was able to play fine.
May I have to disinstall and reinstall? Seriously?
Game crashes on dialog finding a game to join. Less than 24h after installing on W10. Find a match works fine. Can join any game.
Crash reporter doesn’t work! Buttons are grayed out, when trying to unclick I agree, it crashes too.
Where can I reset UT?
Seams to be server-side error. Now quick play is working again.
I have the same problem on Ubuntu 14.04.

HI everyone,
This appears to have been fixed internally and the fix should be released in a future build.
