Weird client bug thats quite frustrating {Client}

So I'm having a weird forced dodge problem continuously. It appears to only happen in promotional series matches. I que for a match and accept normally, the champ select works fine at first, however at some point usually in the ban phase it randomly freezes the image, I'm still able to chat in the lobby, but it doesn't update the champ select for me, this ends up booting me from the game as I can't select a champ after that. Sometimes it will show the "disconnected from league screen" during this process, however, my internet is a stable 50 ping when I get in game normally and my normal internet (chrome) will still run fine as if my internet has no issues. Also after the "dodge" it will report "a player has left the game" in the top right, and not report my name as if it was my fault, in fact, it goes all the way to reque me as if I don't have a leaver penalty, this "que" is under my assumption infinite as I waited 16 minutes in it with no match. Whenever I attempt to cancel the que, either through hitting the x on the upper right que timer or by canceling it from the lobby screen using the cancel button the x will have no response while the cancel button will play the normal animation and sound but not actually do anything. This forces me to restart my entire client to even play a game excluding the que and league penalty. Originally I considered this an isolated issue from my promos to s3, but it also repeated in my promos to s2. This is a frustrating issue as it not only delays my play time significantly but also loads me up with losses, I would appreciate any support that could explain why I'm having this issue. I'm on the new client beta as well if that could be relevant. I'm not sure if this error was caused by the new update or not as I was only ranked 7.6 and just entered a promo series in 7.7 However, this error has happened with every series I've entered so far, and not at all in non-promo matches [zombie-nunu-bummed]
