van 185, -102 and val 5 error codes

I get those error messages when my game crashes (around 2-3 times per game). I even got a 30 minute ban for "3rd party" but I don't have anything of that sort, unless some firewall is interfering but I allowed vgc through my windows firewall so idk. I can't even login to my riot support for whatever reason. SO YEAH PLEASE HELP :((
