Bug Report: Flux Model Loading Failure in Director Automatic Mode

I'm encountering a reproducible error in Director Automatic Mode where image generation fails before any clips are created.

Affected Model: Affected Model: PI-FLUX.2 Dev NVFP4 32B and maybe other NVFP4 and others.

Error:

Error(s) in loading state_dict for Flux:
size mismatch for double_blocks.0.img_mlp.0.weight:
checkpoint: [36864, 3072]
expected:  [36864, 6144]

The Director pipeline then terminates with:

RuntimeError: Generation failed

Expected Behavior

Director Automatic Mode should load the selected Flux model and begin image generation successfully.

Actual Behavior

The Flux model fails during checkpoint loading due to a tensor size mismatch, causing the entire Director pipeline to abort.

Notes

• This appears to be an architecture/checkpoint compatibility issue, not a prompt or project issue.
• The checkpoint dimensions (3072) do not match the model architecture being instantiated (6144).
• The problem is reproducible and occurs before image generation starts.
• Please verify that Director Automatic Mode is loading the correct Flux architecture for the selected checkpoint (or selecting the correct checkpoint for the architecture), particularly when Auto mode chooses the image model.

Thank you!
