Game crashed 'd3d12 failed to create resource for texture' during the breachstone boss fight

Spent numerous hours to collect 300 breach splinters and finally got a breachstone to fight the boss...
Cleared the realmgate map and got to the boss....after a few seconds of the fight, the game crashed with the error message saying 'd3d12 failed to create resource for texture'

The Breachstone is gone.
All those hours and effort I put to collect the breach splinters are gone.
All I got from the fight after restart the game was couple of breach rings (normal/magic) and Oaksworn Shield....This is very very very very frustrating.

I wish there's way for the developters to take a look at my game log and get my breach stone back..at least come up with some solutions so the same issue doesn't happen again in the future..
