Start by downloading the attached result.zip and reproducing the failure on Windows with arXiv paper 2510.08391v2. Read the included terminal traceback to identify which PDF-generation stage fails, then trace that stage in the Python project. Done means the paper translation completes and produces a readable PDF.
