Torch not compiled with CUDA enabled

So My PC specs are :-
CPU :- AMD 7 5800x
GPU :- AMD 6600xt
RAM :- 16GB
VRAM :- 8GB

I had working comfyui using this :- https://youtu.be/8rB7RqKvU5U?si=-DxRLZKw3xy4bqPY

everything was working correctly until this commit in the main branch :- [Stable Cascade Stage C.](https://github.com/comfyanonymous/ComfyUI/commit/f83109f09bec04f39f028c275b4eb1231adba00a)

and I started getting this error :- "Error occurred when executing CheckpointLoaderSimple:

but this solved when I rolled back to this commit in the main branch :- [Stable Cascade Stage A.](https://github.com/comfyanonymous/ComfyUI/commit/5e06baf112c0ccccbf51f0249abb3e121147f2d3)

I don't know why this is happening ? would be glad to have this solved

Thanks
