My 4090 Can’t Run Fortnite

So I built my first high end gaming pc about 2 months ago and I can run any game without issues but Fortnite. I’ve tried uninstalling 3 times and using the lowest settings possible and running it on “performance mode” but I still get really bad frame drops and stutters. I really don’t know what the problem could be since I can run bo6 perfectly and other demanding games. I have a 1440p 360hz Alienware monitor. My pc specs are: Asus Tuf Gaming 4090, Ryzen 7 7800x3d, 64gbs ddr5 ram. (Sorry for the long post, I just really wanna get this fixed)
