AttributeError: 'list' object has no attribute 'dtype'

I also faced same issue

[badraymen]

@lmxyy I found the solution but it's temporary, the problem is not with RES4LYF only, even with ksampler and others, i just toggled comfyui to version 4.0 and qwen work again, but unfortunately new encoder of qwen image edit 2511 disappears from list as i think its linked to version 6.0, so conclusion to work qwen 2509 nunchaku and lora nunchaku we have to pass a comfy vui4.0 and to make qwen work 25 111 must return to v6.
From what I understand, there needs to be an update but I don't it's for nunchaku or comfyui.

Same issue here.

[markha1]

they broke everything for z nunchaku which is in bad quality

[teiteilingtei]

The old version of nunchaku is also wrong.

[Milor123]

I have same issue and normal ksampler. I am using Nunchaku Qwen-Image DiT Loader

for normal ksampler i get this:

'list' object has no attribute 'dtype' 

for SharkSampler_Beta

'NoneType' object has no attribute 'extra_options'

This used to work but I don't know what happened, it broke in some update about a week ago and it's still broken

More info for debugging:
This only happens with a reference image added either via 'TextEncodeQwenImageEditPlus' or 'ReferenceLatent' node.
Without any reference image -basically text to image- it runs without error.
