Telemetry Top 10 ComfyUI Errors in Wonderful Launcher

This report summarizes the ten highest-volume issue families in the production telemetry snapshot queried on April 17, 2026. It is meant to help users and support operators separate noisy warnings from the problems that most directly block setup and workflow success.

These counts show event volume, not just unique users, so the biggest buckets are useful for prioritization but should still be interpreted carefully.

Top 10 issue families

1. Missing Plugin Module Warning Is Not Always Fatal - 5,159 events across 76 installs
2. Triton Missing or Unavailable in ComfyUI - 919 events across 97 installs
3. SageAttention Missing in ComfyUI - 297 events across 35 installs
4. InsightFace Missing in ComfyUI - 255 events across 12 installs
5. Piexif Missing in ComfyUI - 135 events across 15 installs

9. Deployment Failed While Installing ComfyUI-Manager - 23 events across 16 installs
10. Python Out of Memory in ComfyUI - 20 events across 8 installs

What matters most

• The biggest telemetry bucket was missing-module noise from plugins and optional backends.
• The biggest user blockers were deployment failures and download failures.
• A smaller but important cluster involved Python-side memory exhaustion during real workflow execution.

Also worth watching

Outside the top-ten cutoff, the same telemetry snapshot also showed CUDA out-of-memory incidents, HuggingFace 403 and IOException download failures, and a small but high-confidence XamlLoadException startup crash cluster.

How to use this section

• Start with the error guide that matches the package name or deployment step in your log.
• If your launcher still reaches the ready state, treat missing-module warnings as suspect but not automatically fatal.
• If setup stops before first launch, prioritize the deployment and download guides first.
