I just purchased the Early Release today, and it seems I can't launch the game at all. I have a fairly simple system, Windows 11 w/ AMD Radeon 580X.
When launching the game (via steam or explorer), the helicopter splash screen is displayed and the bar progresses to 86%...then just drops back to the desktop. I have updated adrenaline drivers, tried 3 different 'flavors' of beta version in Steam, uninstalled and reinstalled, deleted all local files (in Steam Library and My Games folder), etc. It always dies in the same place.
I've also gone into the json display file and set fullscreen to 'false' and manually set a lower resolution than my monitor's native...the game now launches in a smaller, windowed mode, but still crashes.
This seems like a simple game...not sure why I can't at least get past the splash screen.
