I maintain a ComfyUI workflow that suddenly refuses to launch—every attempt ends in an immediate crash before the interface even appears. I have a four-hour window set aside to pinpoint and resolve whatever is causing this startup failure. The job is entirely focused on debugging existing code or node configurations; no new features or performance tuning are needed. Once you connect, we will reproduce the error together, inspect the logs, and trace the culprit module, dependency, or malformed workflow file that brings the program down. Please be comfortable working live (screen-share or similar), navigating ComfyUI’s Python back-end, and patching or rolling back packages on the fly. Deliverables (end of the four hours) • Running ComfyUI instance that starts cleanly on my machine • A concise note describing the root cause and the exact fix applied (file paths, code snippets, or version changes) • Any quick sanity test that proves stability on restart If you can slot this in immediately and are confident with ComfyUI internals, Python, and GPU-based toolchains, let’s get this crash sorted.
