Start with the problem in front of you.

Distinguish 5B TI2V from the 14B text/image-to-video routes. A shared Wan 2.2 label does not make weights, VAE, encoder and latents freely interchangeable.

An AttributeError in a color node may concern an old mapping, not a missing module. Identify the exception before choosing a package repair.

A connected socket and accepted queue request are not a result. Check client_id, prompt_id, terminal events and history together.

The named Python module can depend on another missing or incompatible runtime library. Native import failure is different from a top-level Python package simply being absent.

An extraction, Git checkout or node build can fail because of one long path. Identify the failing tool before changing system policy or relocating an existing Python environment.

This Windows error concerns committed system memory. It should not be treated as VRAM exhaustion or proof that a safetensors file is corrupt merely because it appears during model loading.

A source-based reference to Wonderful Launcher, which lists the same operator as ComfyUI World; follow the original download and policy links.

A normal data-dependency loop prevents a valid execution order. This is different from a supported loop/control-flow node with explicitly defined semantics.

A displayed result, screenshot or resaved image may not contain recoverable workflow data. This alone does not indicate a broken import function.

An API execution node needs class_type. The same missing_node_type category may also report a class that exists in the request but is unknown to the backend, so read message and extra_info together.

Preserve an export before investigating draft storage, file downloads or API-format confusion.

pip can show xFormers as installed while its C++/CUDA extension fails to load or no attention operator supports the input. Package presence and usable GPU kernels are separate checks.
