The issue itself is occurring because the 4-channel latent generated from EmptyLatentImage is not being converted into the 16-channel latent that FLUX or SD3 uses, when it should be.

Try disabling all custom nodes and attempt it again.

If the same issue occurs even without custom nodes, please attach the workflow.
