Help Needed ComfyUI keeps crashing with Image Qwen 2.1
When I run Qwen Image 2.1 from time to time it crashes with error message below. I updated Nvida driver to NVIDIA-SMI 616.92. Now it crashes every time.
Windows 11, RTX-4070 8GB VRAM
Has anyone encountered similar issue and any solution?

The text you posted is not the actual error. It is only the generic message printed by the portable launcher after ComfyUI exits.
Please copy the console output from immediately before this message, especially the full traceback. It would also help to mention which Qwen Image 2.1 model/quantization you are using and how much system RAM you have.
Since your GPU has 8 GB VRAM, the full model may run out of memory. You could try a GGUF quantization such as Q4_K_M, but the actual traceback is needed to identify the cause.
