ComfyUI for RTX 5090

I'm having trouble with my current ComfyUI setup because it's outdated. Looks like I’ll have to download a fresh copy, but I really want to avoid going through the nightmare of fixing dependencies, PyTorch versions, and all that again.

Does anyone have the latest version of ComfyUI that works smoothly on RTX 5090 or the new Blackwell series GPUs? I’d really appreciate if you could share it or point me to a reliable source.

Thanks in advance!
