Research direction

Reproduce the clean-install startup path by running update.bat and run.bat, then inspect the traceback through transformers/utils/import_utils.py and the installed urllib3/util/ssl_.py. Determine the dependency incompatibility that prevents transformers.models.clip.modeling_clip from importing; done means the application starts and reaches the web UI.
