FPS drops to 0

I have a high end gaming pc and don't understand why I sometimes get 0 FPS for a second in Phasmaphobia ? it only happens in Phasmaphobia. My specs: Sparkoon 700w Rtx 3050 8gb i5-11400f 32gb ddr4 3200

So recently my fps has been dropping a lot I don't really know a lot about this stuff but here are my specs I normally get 160 and run on all low setting please also tell me if something is wrong Thanks

Status: Solved by downgrading to Windows 10 Oct. 2018 Update. Any help is highly appreciated, thank you very much. Let's start with my system specs: i5 6500, GTX 1080 Ti, OS and Game installed on SSDs, 16GB of RAM. When the problem started appearing: I've reinstalled Windows, that's it...

My processor feels very slow sometimes and even when I tried playing survivio, a 2d game on a website, I was lagging very badly. I can run fortnite at about 60-100 fps, which is ok but when I try to run MINECRAFT, a game anyone can run (same as survivio) I get like 40 fps. Someone, please help me.
