CitizenFX Fatal Error: ROS launcher failed before it could give an all-clear?

Whenever I launch my game I get the error “ROS launcher failed before it could give an all-clear?”. I’ve reinstalled GTA like 3 times and it hasn’t fixed it. I also reinstalled FiveReborn many times. I also updated my .net framework.

GTA Version: 791.1
Up to date:? Yes
Legit steam copy
Error screenshot:
GTA Folder:
FiveReborn Folder:
.dmp files: no idea what this is

Thank you in advance for your help!

Did you start FiveReborn as Administrator and in compatibility Mode for Windows 8?

Compatibility mode seemed to remedy the problem! Thanks!
