I had a similar error in another node, replacing DualCLIPLoaderGGUF with gemma_3_12B_it_fp4_mixed(.safetensors) with the .GGUF version (gemma-3-12b-it-Q5_K_M.gguf) helped.

And the second one:

After updating ComfyUI, I encountered the same issue you had. (81 node)

I managed to figure out that the problem lies in the get_key_weight function. The line weight = getattr(op, op_keys[1]) strictly requires the layer to have a .weight attribute. If it doesn't (as is the case with custom or quantized layers), the script crashes.

Here's how you need to modify the get_key_weight function in the model_patcher.py file (...\ComfyUI\comfy):

def get_key_weight(model, key):
    set_func = None
    convert_func = None
    op_keys = key.rsplit('.', 1)
    if len(op_keys) < 2:
        try:
            weight = comfy.utils.get_attr(model, key)
        except AttributeError:
            weight = None
    else:
        op = comfy.utils.get_attr(model, op_keys[0])
        try:
            set_func = getattr(op, "set_{}".format(op_keys[1]))
        except AttributeError:
            pass

        try:
            convert_func = getattr(op, "convert_{}".format(op_keys[1]))
        except AttributeError:
            pass

        # --- MODIFIED PART ---
        # Using safe attribute access (will return None if it doesn't exist, instead of crashing)
        weight = getattr(op, op_keys[1], None)
        
        if convert_func is not None:
            try:
                weight = comfy.utils.get_attr(model, key)
            except AttributeError:
                pass
        # ---------------------

    return weight, set_func, convert_func
