Game Crashes if screen saver turns on

Please attach the complete output of the "Development console" tab of the launcher.

• Click the text, press CTRL-A to select all, then CTRL-C to copy, and CTRL-V to paste in a comment on this ticket.

If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

Here's what the information says. I tapped the windows key midgame to toggle to chrome and got a white screen in the launcher, then closed program and reopened.
