i need help. Whenever i go into a match i spend about a minute on a loading screen then get kicked out and get a penalty. On the rare occasion i do get in i am on the agent select screen but with no agents. What do i do?

I'm a plat 2 player who recently ranked up from gold 3 to plat 2 within the beginning of the act and I play the game on a daily basis. But for the past 10-12 days or so I feel like my skills in the game in general have decreased drastically...
