Before you ask, I did the following:
Disabled "Pause Game on Focus Loss"
Deleted Cache.xml and cache folder TWICE.
Tried launching the game from Fullscreen and Borderless Window.
Ran the .exe normally and as admin.
The client will always crash on the orange screen before the server list.
Here is my included DMP crash file if any Dev wants to see what's wrong. https://www.mediafire.com/?mpyr0oygkzb8kzn
Specs: i5 4690k/GTX 970. Have FiveReborn and GTA V running on the same SSD (C:).
