I had the same issue just now where the minions got stuck in mid lane fighting invisible enemies and wouldn't progress further but on the hidden king side around 29 minutes. Match id: 61380581
Same thing is happening to me since at least a week ago. Over the course of the game the VRAM gets used up and frames drop to around 10-15. I'm also on Linux
I had the same thing happen to a teammate who was playing sinclair, after stealing the viktor ult he became invisible. I also used the attach ability on him as rem by accident and it seemed to have crashed my game, after which it crashed 2 more times upon launch. Match id: 52808292
