Error when running Flux

[Weatherby43]

I tried doing a pull and updating forge and got this error. Then I saw a post about doing a clean install, so I used Illyasviel's zip'd installer. That worked..sort of. I had issues with xformers version and torch version. Got those sorted, then was back to the same original error. This is the error I got before doing the clean install, and now get again:

RuntimeError: The expanded size of the tensor (1) must match the existing size (64) at non-singleton dimension 0. Target sizes: [1, 256, 256]. Tensor sizes: [64, 256, 256]

Model selected: {'checkpoint_info': {'filename': 'K:\AI\forge20\webui\models\Stable-diffusion\flux1-dev-bnb-nf4-v2.safetensors', 'hash': 'f0770152'}, 'additional_modules': [], 'unet_storage_dtype': None}

Also, VAE: my vae/text encoder field is blank. If I select the original AE.safetensors that was posted with Flux, I get an error about mismatches, which tracks because it's FP8 and the model here is nf4. But, when I don't download a vae, the drop down is blank.. no NONE or AUTOMATIC options... I don't know if this is related or not, but figured it worth mentioning.
