Hi, I have almost exactly the same setup and the same issue.
Windows 10 Pro, Core i5 3570K, RX570 8GB, 16GB DDR3. Game installed via Xbox app, I didn't purchase it as it's on the games pass for PC.
Graphics drivers are latest. Game crashes to desktop with no error message randomly, normally I can get a good hour or two in. The crash will usually happen when fast travelling, loading an area, or in one instance every time I tried to talk to Catherine in Fallbrook, until I reboot.
Sometimes the crash happens at the same point repeatedly, but on reboot the crash will no longer happen at that point, but occur again somewhere else.
I will try to play tonight & check event viewer and post the log when it crashes.
