D3D11 unknow error

Hello GGG Team,

I am experiencing a very strange technical problem with POE2.
I am currently playing my third character in Fate of Vaal, a Blood Mage. Since the endgame content, this character has been causing system crashes. I have checked all parameters such as graphics card drivers, chipset drivers, GPU temperature, and utilization metrics.
Other characters run without interruption.
The D3D11 unknown error occurs and the game closes. This happens mainly when the effects on the screen fade away, not when they are fully present.

Are there any experiences or solutions for this?
I would be very grateful if you could check this out.
