Error after updated to ComfyUI 0.3.68

[Orenji-Tangerine]

I noticed ComfyUI only replaced the workflow version and dont know if they are related but ComfyUI failed to load after the update. It works fine when I revert back to the older versions of ComfyUI

No sure if it is after this update

`ImportError: cannot import name 'apply_rotary_emb' from 'comfy.ldm.lightricks.model' (E:\SD\ComfyUI_windows_portable\ComfyUI\comfy\ldm\lightricks\model.py)

Cannot import E:\SD\ComfyUI_windows_portable\ComfyUI\custom_nodes\ComfyUI-LTXVideo module for custom nodes: cannot import name 'apply_rotary_emb' from 'comfy.ldm.lightricks.model' (E:\SD\ComfyUI_windows_portable\ComfyUI\comfy\ldm\lightricks\model.py)`

ltx_model.py
我把报错的旧函数移除了，并修改成了新的函数，目前加载正常。不清楚使用过程中是否有问题。仅供参考

root-cause: the node package is still trying to import apply_rotary_emb from comfy.ldm.lightricks.model, but with updated version of ComfyUI (or the core module), that function no longer exists.
