_No response_

The report provides no file, test, model, workflow, or reproducible input beyond the tensor shape error. Start by reproducing the sampler failure and tracing where the invalid reshape is raised; done means identifying the responsible workflow or model condition and confirming the sampler no longer reports the error.
