I have heard a lot of Pro guides and Immortal/Radiant players saying that players in bronze/silver should play with friends instead of solo queueing.... Is this true? If yes what should I as a person with no "friends who play valorant" do...

Cannot open my game, if i do it closes with VAN 68 or 79 or something else. Cannot press start, cannot do anything, anyone else having this issue ? ​ UPDATE: Game is back
