Hi, you're not alone. In my case it is a stornvme error that makes the drive disappear. I also have a 990 pro and tested a 980 pro as well.
Do you have a single drive or what's your storage config exactly? If you have the game installed on a 990pro as a D: drive, it might be the same issue that I'm having.
Thanks for your response. Just to clarify, my 990 Pro is installed as my C: drive and I have never had any issues with the drive disappearing or failing. I played the game for more than 200 hours without a single problem, and then suddenly constant crashes started happening out of nowhere. I am completely sure the issue is not related to my storage or hardware. This looks like a game-side problem and the developers need to be aware of it and fix it as soon as possible.
I also had over a 100 hours with no crashes. I'm not saying there's anything wrong with your drive, but if it is the C: drive it might not register the error. If you have a spare sata ssd it is worth a try
