"Unable to find workflow" error with the "Image Save" node and webp format

[alex-mitov]

Hi,

I'm often getting an "Unable to find workflow" error when trying to load workflows from images saved in .webp format with the "Image Save" node. With images that are a few seconds apart, some of them will have this problem, and some of them won't. It's really odd. I don't get such errors when I save as .png. Any idea why this might happen and how to avoid it?

My ComfuUI version is v0.3.31-3-g80a44b97 (2025-05-04).

Attached are a couple of workflows. One of them is loading and the other won't. Can anyone check and see if both load for you?

Thanks in advance!
