I mentioned it to you elsewhere, but DX12 is not officially supported and is not recommended to be used.

The developers have warned people not to use it, and have mentioned that it will be prone to crashing.

You can maybe do some diagnosing of your own, perform the hard reset, perhaps fully remove and reinstall your graphics drivers, but it's not a bug as such, and afaik there are no plans to support DX12.
