VAN 185, disconnect in the middle of the game

In valorant i get disconnected randomly regularly in the middle of the game for VAN 185 and in League of Legends once the game ends i have to restart the Launcher sometimes due to VAN 185. This problem persists for a long time already and people are dealing with it to this day. Before i didn't have this problem, after switching to a PC, i do. It's not the PC though, it's just some hardware or driver that is incompatible with Vanguard im assuming. Any Suggestions? I keep losing rounds in ranked games due to this.
