Failed to read image file: {e}

Error message

Failed to read image file: {e}

What it means

Wrapped IO error in image_info: tokio::fs::read failed while loading the image bytes, after metadata succeeded and the size check passed. {e} is the OS-level read error (permissions changed, file removed mid-flight, I/O error).

Solutions

1. Confirm the file is still present and readable
2. Check {e} for the OS error cause
3. Retry after fixing permissions or the file state
