I encountered a similar situation in Hugging Face's Gradio Zero GPU space, so I am reporting it just in case. I tried to reproduce the issue with the minimum configuration, but I was unable to reproduce it with just hf_hub_download. There must be some prerequisites, but I have not been able to identify them. The details of the situation are unclear.
I am attaching the log with the HF_DEBUG environment variable enabled.

Actual repo (dedicated for Zero GPU)
