Evidence claims:
- [sourced_fact] Steps: start with --disable-all-custom-nodes (or Desktop settings); optionally disable third-party frontend extensions by halves; bisect nodes with 'comfy-cli node bisect start/good/bad/reset' or by moving half of custom_nodes to a temp folder after backing up; then update, replace, report or remove the culprit. · source: https://docs.comfy.org/troubleshooting/custom-node-issues
- [sourced_fact] Page notes dependency conflicts are common and harder: nodes needing extra wheels (e.g. ComfyUI-Nunchaku), strict pins such as torch==2.4.1 vs torch>=2.4.2, and network failures; it requires Python environment knowledge and gives no specific commands. · source: https://docs.comfy.org/troubleshooting/custom-node-issues
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
