Twice now (crashing on Invasion game mode)

As the title says, I've now crashed twice during the invasion game mode, both times at the exact same moment. In the mode where you travel along the path to the end, upon reaching the end, I sometimes crash. From what I've noticed, both times it's happened while spamming ctrl+2 while playing Poppy, but it doesn't happen everytime. Since it's happened more than once in the exact same spot, I feel like it's not because of me, that it's because of the game somehow. I don't remember the first time, but as it just happened the second time, I can say that I was the only one alive and I had flashed on to the end point (which I've done before without crashing, as have many other people) right before it happened. I crash right before it teleports everyone together. Would very much like to know if it's just my computer or some weird bug with the game mode.

Edit : Just happened a third time under the exact same circumstances (although my whole team was alive)
