What happened?

The original file was found, but the server could not decode the image into a usable form for optimization.

What can you do next?

Take the first action that applies, then run optimization again only when the underlying issue has changed.

  1. 1Upload the image again from the original source file.
  2. 2Check whether the image opens normally outside WordPress.
  3. 3Run optimization again after replacing the image.

Will retry help?
