Cannot execute because a node is missing the class_type property.: Node ID '#107'

Have you installed all custom nodes? And can you leave a screenshot or full logs here?

[xhost007]

The node that fails to load is https://github.com/shizuka-ai/ComfyUI-tbox.

@xhost007 Please use ComfyUI-manager to install the custom node. Additionally, this custom node is not used in the WAN animate template, so it should not be related to this issue.

[xhost007]

That error occurs when trying to install the node manually following the error message.
That being said, the manager finds no nodes.
However, two DWPreprocessor nodes are marked missing. These are used to extract face data and pose data. See capture below:

I also encountered the same problem.
Error prompts are as follows:

Workflow too large. Please manually upload the workflow from local file system.

## Additional Context
(Please add any additional context or steps to reproduce the error here)

[comfyui-wiki]

The node that fails to load is https://github.com/shizuka-ai/ComfyUI-tbox.
This isn't part of the workflow

Please make sure all required custom nodes are installed.

It seems I had a problem with openCV. Reinstalling it (and manually removing older instances) made the workflow now load correctly.
