I had the exact same issue, and this turned out to be a faulty RAM package. OS and regular apps worked fine with EXPO, but BF6 crashed after 2-6 minutes. I ended up changing RAM sticks to another vendor, and it works excellent with EXPO on 6000
It looks like BF6 pushes RAM really hard, and this uncovers issues with it. So I am pretty confident it's a hardware issue, and the game is perfectly fine.
When browsing the forums i see loads and loads of people having problems with the game, so i really doubt its a hardware problem, just doesnt make sence that they all have hw issues. And its just Bf6, they have problem with, all seems to be able to play any other game but this one.
