Research direction
The failing import is interleaved_freqs_cis from comfy.ldm.lightricks.model, so start by finding where the node package imports it. Then compare that module in the ComfyUI 0.28.0 source to see what replaced the function. Done when the node imports and loads on ComfyUI 0.28.0 without the ImportError.

Description
Describe the bug
I'm using ComfyUI 0.28.0, and this node fails to load with the following error:
ImportError: cannot import name 'interleaved_freqs_cis' from 'comfy.ldm.lightricks.model'
Steps to reproduce
- Update ComfyUI to 0.28.0.
- Update ComfyUI-LTXVideo to the latest version.
- Restart ComfyUI.
Expected behavior
The node should load without errors, as it did with ComfyUI 0.27.x.
Environment
- ComfyUI version: 0.28.0
- ComfyUI-LTXVideo version: [nightly]
- OS: Windows 10
Additional context
The function interleaved_freqs_cis appears to have been removed from comfy.ldm.lightricks.model in the latest ComfyUI update. Many users will encounter this issue. Please update the node to be compatible with ComfyUI 0.28.0.
Thank you!
