[PC] ME3 MP Crashing to Desktop While in Game Session

My game keeps crashing to Desktop after playing either 5-10 minutes or getting to wave 4-10. the only way that seems to be the fix is if I stay in a lobby with the same people, but that doesn't last long. I've tried multiple "fixes", but I want to get behind actually stopping it for good or severely minimizing the issue. I've tried setting the affinity for Masseffect3.exe in TM to cores 0 & 1; reinstalling the game; verifying game files (on Steam (bought on Steam), idk how to do it on EA). I don't want to have to download a mod to fix it, I would love to figure out what the problem is first to mitigate to my friends who are getting it on Thursday. 

P.S. Holger1405 if you see this, please try to break down all the technical terms for me, I'm not as computer literate as I thought (seen your other posts you've answered)
