Major lag in lobbies for ranked, unranked, and parties.

Hello, for about 2 weeks now when I try to play a game of battle royale duels or countries both ranked and unranked, and a party lobby using the old ui, there is major lag on the tab when I join and there is a big delay to do an action like reloading, switching to another tab, or going back to a previous link. I have tried everything like removing extensions, clearing cache, turning off and back on for hardware acceleration, and deleting a bunch of ongoing games. It is also really lagging with loading up all of the avatars and with the starting timer going down. Can you please help me with this?

Thank you.
