Crashes when playing in aram?

so has anyone else experienced a random crash that persists as multiple crashes when re-rolling in aram? i have tried it a couple of times now and it causes either the UI or something else behind the scenes to crash 2-3 times before then returning you to the lobby and finalizing your re-roll.

this also happened to have the same crash when i was just sitting in lobby after i got a 15 min ban when the whole client crashed and i had to re-log into the game?
