ComfyUI : Résoudre les plantages sur flux

hi guys!

i need help with my ComfyUI when i tried to launch flux krea or qwen 2.2 image generation.

Since the last update of ComfyUI python 3.13.6 and cu129 I can’t generate complex images! I tried to install triton and sage attention too but doesnt work!

In the last step of creating the image, my PC starts to crash and my PC’s RGB lights appear.

My specs:

RTX4070 12 VRAM

I7 13700K

32gb RAM

and good air cooler

whats happen? look at my screenshot pls

thanks for all !
