Yes, same problem here. Even if I set display to stay on and sleep never, it was still happening. The only thing that would keep it awake was having something running constantly, like music or a video, if I had to leave it idle for a while.
I think I got my answer this morning, however. I had replaced the hdd in the laptop with an ssd when I first bought it, so there was the flash ssd drive that the laptop came with that had the operating system and software, and the second ssd I used for storage. This morning the laptop was throwing errors saying it couldn't find the storage ssd. It's not listed in file explorer, the bios, nor is Samsung magician seeing it, so I think it's a dead soldier. Since that happened, the laptop hasn't crashed once.
Nothing I read in my research pointed to a failing drive, so that was one of the very few things I didn't test. I will post back once I install a new drive to report whether the crashing problem returns or not, just so others having the same issue have another possible answer.
