Constant High Ping at Random Times

I've noticed that when streaming sometimes I get these crazy high ping spikes in Val, even though I check my internet and it looks fine. It seems to happen at weird intervals….sometimes happening half way through a match where I'm doing well, and other times where it starts immediately at the beginning of a round. But usually by the next game its back to normal. To give you an idea of my setup, I occasionally stream/record using a dual PC setup with a capture card. My main system (for gaming) has Valorant and Riot Vanguard installed, but my laptop (streaming/recording pc) also has both the game and anti-cheat installed on it as well. I have it installed on both machines in case I'm ever traveling and I want to play on my laptop. But I was curious.....could running the Vanguard on both machines at the same time cause issues like this? I would think this wouldn't be an issue as it would allow Vanguard to see that no 'extra' software is running on either machine. But now that I've thought about it, I'm curious if this might be partly why this keeps happening because I have stopped using my laptop over the past week and have not run into this issue since.
