Epic games launcher - logged out: now only black screen coming up

I was faced with this problem twice.
The first solution was:

  • open EpicGamesLauncher.exe properties
  • open “Compatibility Settings”
  • Set “Disable display scaling on high DPI settings” to checked.

These steps solved my problem.

But a month later I see black screen again.
DPI settings was already checked.

The second solution was stopping background process “EpicGamesLauncher” in Task Manager. After terminating this process EpicGamesLauncher started normally.
