ping problem

Hi, with my new pc, when I play other games online I have a pretty good ping of 15ms but when I play valo, it gravitates around 1000 ping. I play with a usb wifi adapter, but it's only on valorant that I have this problem. I saw that people were reducing their fps to make it work better so I tried but it didn't change anything. Could someone please help me? Here is my speedtest:
