Hello, I have a problem when trying to open second client (I have PA). It appears quite often, but not always. When I try to open second client window goes gray and crashes in a minute. The problem occurred after I installed odyssey version.

Error: Assertion failed: RenDev [File:.\WinViewport.cpp] [Line: 582] History: UWindowsViewport::OpenWindow <- UGameEngine::Init <- InitEngine P.S. I did full check and restore P.S 2 I think I found a workaround. I'm starting the client on windowed mode so I made a test to star it in full window mode and it seems to be working now. Still do you think there is a general fix for that issue?
