Greetings,

I was hoping you can help. I get black vae preview and error when saving video with your workflow using your inter checkpoint and gemma. I installed quant ops with comfy manager beforehand. I am using a 3090ti. Error below. Also I tried bypassing all the patch nodes and it just generates noise in the preview and video and and noisy audio. I also tried the transformer only with the the quant ops diffusion loader and had same issues, so it isn't just a VAE/Gemma issue as when I did that I used the LTX2 VAEs and usual gemma fp8 scaled. I use other diffusion models and unsloth gguf without an issue.
