Director Clip Regeneration Fails with Float/BFloat16 Dtype Mismatch

What happened?
When regenerating individual Director clips with LTX, the rerun reaches Encoding Prompt and then crashes in the Gemma embeddings connector with: RuntimeError: mat1 and mat2 must have the same dtype, but got Float and BFloat16. The model, image, audio/vocal stems, and pipeline all load successfully before the failure.

I’ve encountered the same Float/BF16 error previously when regenerating with LTX 2.3, and now with LTX 2.5, so it appears to be a recurring Director rerun/regeneration dtype handling issue, rather than something specific to LTX 2.5.

Steps to reproduce

Use Director mode to make clips..
Go to Dashboard.
Click regenerate on a clip to try and regenerate it.
