Crash: Assertion `srcIndex < srcSelectDimSize` failed.

### Expected Behavior

Almost without exception, once the web app has started successfully, I expect all workflow runtime errors to be caught, rather than crashing the comfy process. (I can imagine some security scenarios where you would halt.)

### Actual Behavior

Trying to debug random workflow found online. After resolving all the missing custom nodes and models, I went to run the model. Execution began, and then ComfyUI process crashed.


### Steps to Reproduce

This repro is a bit of a beast. I'm not able to do it without a ton of custom nodes. Check the logs, perhaps there's enough here for you to find the uncaught path?

1. Load workflow from https://openart.ai/workflows/zD2zV9yx45eothT3ulmT
2. Install missing custom nodes
3. Install required models
4. Run workflow
