leaver buster /afk bug

My internet was working just fine , the client too , nothing was frozen i could still interact with my team or enemy team icons, but it didn’t let me join the game , i was stuck with the match loading screen for 10 minutes or so , tried to restart the game to wake up to a remake with me being the leaverbuster and got put into a 20 minute 5 match low priority queue?!?! The game didn’t let me in the match ... I saw it happen to one streamer too , he got through the same experience . What is that and how to not have it happen again ? waiting 20 minutes for a 30-40 minute match is a no no.
