Epic games launcher stuck on "please wait" at login - Programming & Scripting - Unreal Engine Forums <–This problem, with no solution.
The suggestion with -OpenGL just insta-crashes it with the “Send Bug Report and Restart” “Send Bug Report” window. It’s also not a firewall issue since it persists even with that disabled. It was working fine before I did a clean upgrade to Windows 10 and tried to reinstall it. I also tried to get the debug log with the -debuglogging command but there’s nothing in the available AppData folders for Epic Games. Any ideas?
