Description

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

I would like to be able to install the ComfyUI-LTX Video custom node and have it work.

### Actual Behavior

I can install the node, but there is a conflict.

### Steps to Reproduce

- Since installing the new update, I can no longer use any LTX workflows, as I am unable to install the custom node comfyUI-LTXVideo.
-I tried to automatically install the ComfyUI-LTX Video custom node but without success, then go to custom node manager and try to install it directly, still nothing. After I opened the folder D:\Comfy-Desktop\ComfyUI-Installs\ComfyUI\ComfyUI\custom_nodes\ComfyUI-LTXVideo and opened the cmd command trying to install it via git clone https://github.com/Lightricks/ComfyUI-LTXVideo.git, still nothing I manually downloaded the custom node to put it directly in the folder D:\Comfy-Desktop\ComfyUI-Installs\ComfyUI\ComfyUI\custom_nodes, still nothing delete the node reinstall nothing, activate the nodes one by one but still nothing, I don't know what to do anymore.

Research direction

Start with the traceback in nodes.py and reproduce the custom-node load through custom_nodes/ComfyUI-LTXVideo/__init__.py. Inspect the import in pyramid_blending.py and the installed kornia package in the reported virtual environment. Done means ComfyUI loads the custom node without the ImportError and an LTX workflow can be used.
