I'm also having this problem, but the worst part is, it crashes whenever I'd stay long enough in my endurance runs.
The first crashed I experienced when I do some endurance runs a week ago.
It crashes around 225 mins+, lost around 300+ Steel Essence. my nVidia driver version this time is 531.41.
The second crash happens just earlier.
this one crashed around 176+ mins. lost around 600+ Steel Essence w/event booster. nvidia driver version at this time is 531.79.
Driver update seems doesnt fix the issue. Now I'm hesitant to do more endurance runs despite having event booster.
I already sent a request to support but I doubt it will be fixed right before the event booster expires in few more days.
