I have recently downloaded Razer Cortex, but after a few days, my game started crashing about 20 seconds after the game launched. After I uninstalled some drivers and software, the same issue persisted. I uninstalled Razer Cortex, and then it never happened again. After reinstalling it, it kept happening no matter what was installed or uninstalled. Also, Razer Cortex does not optimize your computer. It makes your startup times longer and shutdown and Restart times (In my experience using this application). The application's code is somehow violating Fortnite's Anti-Cheat. This application is not an "Optimizer." for most games with Easy Anti-Cheat.
Any help is appreciated (If it resolves my problem.)
