The crashing is caused when you place a custom block on a new chunk. If that chunk already has a custom block on it, the client will not crash. But...

Make sure you have Triton already installed (see https://github.com/comfyanonymous/ComfyUI/issues/7421#issuecomment-2763311543) In the ComfyUI desktop open up the terminal and navigate to the **.venv** folder run `pip install SageAttention`
