Custom Node Testing

I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Your question

Hello,
I try to use Wan 2.2 for the first time with ComfyUI, i installed ComfyUI app on my desktop, opened the template Wan 2.2 5B video generation, clic run with all default settings and get this error in the main.log file :
[error] Python process exited with code 3221225477 and signal null

The workflow seems good, takes a few minutes to get to 10% and then there is a red message in the top right corner sayin Reconnect and the wotkflow stops.

I have to say my computer is a Shadow PC, a virtual machine I pay for every month and might not have full controll on RAM but here are my setup:

我发现问题是：因为新版本的ComfyUI它会强制要求我们使用的英伟达驱动更新到更新的版本，我使用旧驱动跟使用旧版本的ComfyUI不会出现提及的这个问题，而当我使用新版本的ComfyUI软件就提示各种错误了，后面我更新了英伟达的驱动就没问题了，也许对你有帮助。

@dosubot[bot] commented on GitHub (Apr 22, 2026):

Hi, @comfy-pr-bot. I'm Dosu, and I'm helping the desktop team manage their backlog and am marking this issue as stale.

Issue Summary:

You reported a Python crash with exit code 3221225477 when running the Wan 2.2 5B video generation template on a Shadow PC VM.
The crash occurs despite having sufficient RAM/VRAM and disabling custom nodes.
Some users suggested the issue might be related to NVIDIA driver versions, with fixes reported after updating to drivers like version 591.74.
However, you noted the problem persists even after updating drivers, switching to studio drivers, and downgrading ComfyUI.
Further investigation into driver compatibility and ComfyUI versions is still needed.

Next Steps:

Please let us know if this issue is still relevant with the latest version of the desktop app by commenting here to keep the discussion open.
Otherwise, this issue will be automatically closed in 7 days.

Thank you for your understanding and contribution!
