Cloudy with a small chance or crashing

Here we were, after years of not playing, me and 4 friends, excited to play again, we made a 60min treaty lobby, somehow we found 3 people wanting to play 5v3 knowing we were all garbage having not touched any aoe in years. We built our base, admittedly, we didnt do great. The timer started counting down, 1 minute left, we loaded up a huge suprise force to flank them. BOOM, battle starts, our cavalry rushed in to... 5 people crash, big lagspike, their AOE stops responding and theyre out of the lobby. 3 of us including me, the host, are left, we fight for another solid 10 seconds, boom, all 3 of us have the game freeze and then proceed to crash our entire pc. I dont know if this is a known bug that has some easy workaround but to say we were not amused is an understatement. I just want to enjoy the game again.. i was hyped:(
