Yes the BG’s are crashing. I’m not sure why this hasn’t even been acknowledged by Blizzard yet (however they were quick to nerf honor…).
I suspect someone might have to put together a win trading addon to get Blizzard’s attention, although in some games even a 5-cap AB or chain 3-cap WSG isn’t fast enough.
Edit: If someone does put together a win trading addon please post it in the main forum. It doesn’t even have to actually work or do anything, but we can bump it repeatedly to get attention.
