4-26% packet loss when playing CSGO after using Cloudflare

Hi so, today i tried to use Cloudflare to stabilize my R6 game because their servers are kinda acting up, but after a few hours which i left my PC and then i start up my CSGO it has 90 ping which is unusual then realized Cloudflare is still on so i switch it off and then the ping is normal but the Loss appears at a very unusual rate which from 0% to 16% stable and spiked to 33% at some point
this also made my download speed in Steam which is from 10 MB/s to 3.8MB/s anyone can help me fix this to normal?
