[LatentBatch] Sizes of tensors must match except in dimension 0. Expected size 4 but got size 16 for tensor number 1 in the list.

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

I would want images generated may be slow but still run with my System with RTX 3060 Ti. The Model/Checkpoint is SD 3.5 L. SDXL and Juggernaut XL running great. When I run SD 3.5 L with the same workflow, I am facing this issue.

### Actual Behavior

Using pytorch attention in VAE
Using pytorch attention in VAE
VAE load device: cuda:0, offload device: cpu, dtype: torch.bfloat16
no CLIP/text encoder weights in checkpoint, the text encoder model will not be loaded.
Requested to load AutoencodingEngine

### Steps to Reproduce

You can try to run [SD 3.5 L ](https://civitai.com/models/880208/sd-35-fusion-8-steps-merge-full-model-and-lora-version) using RTX 3060 Ti. I have attached the workflow. Upload an image and a batch sampler Load Image and EMpty Image.
