Inconsistant crashing

Sometimes my game will crash, but when and how it manifests varies. Sometimes when I'm trying to start a game it'll close and tell me I'm not connected to the internet when I very much am, sometimes it'll just freeze during loading, sometimes I get a bugsplat when trying to load, but recently I got a bugsplat midgame. Thankfully I was able to connect right back (we still won) but this is very frustrating because I don't always get so lucky.

And it's frustrating feeling like my level of success depends on if the game will actually function or not.
