Same for me Patrick, the Realm does not show up on my account. Making me think this could be a server-side issue perhaps and it's trying to render a message which is causing the crash?
And now the crash is back, even with latest drivers.
Same issue. I managed to buy a realm and set it up, but I wanted to log out to change the seed but I got a gateway error of some sorts (didn't grab it in time) and now it's just showing an empty menu which crashes after some time.
EDIT: Latest NVIDIA driver fixed it?
The Realm Screen froze for me too while changing some settings. That was when this started happening. After updating my drive it started working again, but I changed another setting and then it froze and now the crash is back.
