Lately error and some time Direct X problem?

I am having this problem since the update and it's kinda always game shut down! What's the problem lately? When playing a story line, the graphic error and kick me out! I need to do it and kill the boss again!

Any solution or helper?

I think I am having the same problem.

I am routinely suffering crashes when the Shaper interrupts boss fights, or when I kill the boss (and Zana says something, as the Memory shard drops - I don't even see that happen).

I just killed my first Guardian, and the moment he died, the game crashed, and I am unable to return to the Wastes of Lunacy. Although I absolutely killed the boss, I did not receive credit for beating the map, as the memory fragment is still on the ground in the un-recoverable instance.

Pretty big bummer, I feel like I should avoid the current content, as I have not crashed other than these situations.
