AVIF conversion becomes black and white.

[ecker00]

I don't know much about the AVIF format but thought I should share a failing file. Might be the alpha channel playing tricks on the converter or something. I have pulled latest version. Tried converting from avif to jpg, png and webp, all same b/w result.

Here is the offending file: https://framerusercontent.com/images/7Nhoxwn9eWYrqKjEewfXutR90U.png?scale-down-to=1024 (can't attach it, not supported format on github). If the link becomes unavailable, it is the small top left logo on https://www.comfy.org/ and the output of the conversion looks like this:

The expected output from another online converter (https://www.freeconvert.com/avif-to-png) was this:

I have not tested other files, just reporting what I found in this one case. Here is the docker logs attempting convert to webp:
