I Double click my ComfyUI icon and it opens and says "Unable to start ComfyUI Desktop v0.4.18. Not sure if this has anything to do with video, but the image creator works if I run it from the “ **run\_nvidia\_gpu** ” file in my “ **ComfyUI\_windows\_portable** ” folder on my desktop.

**Generating images: WORKS fine in browser**  
However, I can run the program in my browser and I can drop in a **workflow.json** example and it does produce images as expected.

**Gengerating video: DOES NOT WORK in browser**  
Everything is fine until I drag in the suggested “ **ltxv\_text\_to\_video.webp** ” file and it has a few node errors.

Once I drag in the .webp file is says this:

**Warning: Missing Node Types**

**When loading the graph, the following node types were not found:**

\*\* LTXVConditioning\*\*  
\*\* EmptyLTXVLatentVideo\*\*  
\*\* LTXVScheduler\*\*

**No selected item**

**Nodes that have failed to load will show as red on the graph.**

If I ignore that pop up and click queue Prompt is says “Cannot execute because a node is missing the class\_type property.: Node ID ‘#69’”

Not sure how to go about fixing this… Thank you if someone can help with this!!!
