I often have the game crash on start up. And occasionally at other times as well. Thankfully, the mid-game crashes have decreased a lot for me personally (fingers crossed that saying that out loud doesn't increase them again), but the start up ones still happen quite often. Sometimes daily, and sometimes 3-4 days a week.
I always try to send the on-screen report thing, and trust that those go somewhere useful. I've always assumed that the "various bugs and fixes" includes working toward this, but understand that finding all of them is probably like finding a ton of needles in a ton of haystacks.
Usually the start up crash that I get will happen once, and then it will let me in. A few times it has made me restart 2 or 3 times, but usually lets me in after that. I thankfully haven't had it where I can't get in at all. (Although I know that there may be others for whom that's been the case).
I've tried all various suggestions that I've seen made (verifying files, updating, restarting, checking connections, etc.), but since I'm not a computer genius and don't live with one, and since it's mostly happening for me at the beginning of a play session instead of in the middle so I'm not losing things, I've mostly just sort of accepted it as part of my log in/load in time each day. (While still sending the report, of course, in case it helps the devs identify the problem).
At any rate, just wanted to say that it's a real thing for me as well, and not connected to negativity about the game itself. I just don't think to mention it very often because it's become a part of my routine.
