Game search crashing without valid reasons + People drop far mor often at loading screen and get 5 min cooldown for no reason

Hi there,
Since the new update few days ago (18th August) i realize more loading screen crashes as well as game lobby crashes in team ranked where people do not appear or 1 second after the lobby opens it closes directly again.
I also wrote with a guy who crashed at the start of the loading screen and I dropped too after 3 seconds.
He wrote that he did nothing as well as getting 5 minute cooldown…

Please fix these issues, I hate waiting already 4-10 minutes because my premade team is diamond 3 to conq 1 getting doged most times.
