Reproduce the reported generation and upscale failures, then inspect extensions-builtin/sd_forge_freeu/scripts/forge_freeu.py and modules/sd_samplers_common.py at the traced lines. Separate the FreeU model_channels error from the BFloat16 image-conversion error, and confirm that the affected workflow completes without either exception.
