Lag switchers in PvP

Anyone else be playing a game winning or even then outta no where you’re hit with lag but the other team is not effected by it, even though you played many games before and after this match with no issues, it’s happened twice now and I’m suspecting lag switchers, if everyone was lagging I would think the server but only my side lags, I checked my internet and had Open NAT, 0% packet loss, and 46ms
