Ranked keeps crashing after latest update - losing hundreds of RP

Is anyone else having this issue?

My game runs perfectly fine in casual matches, but almost every time I play ranked it eventually crashes. Sometimes I can get through two or three games without any problems, but sooner or later it crashes again. 

The worst part is that when I restart the game and try to return to the match, I often get the message "Couldn't join - forfeit match" and end up getting penalties, which feels incredibly unfair bc it wasn't my fault. This has happened five times in the last three days, and I've lost over 400 rp, if not more, because of these crashes and the automatic penalties. At this point I'm seriously considering taking a break from the game until the next update, in hopes that this gets fixed.

The issue only started after the latest update. Has anyone else experienced this issue? and if so, are the developers aware of this?
