Failing webp image

I have a picture tag with several sources for fallback, historically I have had webp for chrome/firefox and fallback to jpg for Safari.
Since Safari 14 on Big Sur now supports webp, it tries to load the webp source, which is great!

Unfortunately, it fails to load the largest size in my srcset. I have tested the offending image on Chrome and Firefox, and it works there. 
All the other webp sizes in my srcset loads fine on Safari, just the biggest.

I have attached the failing image.

My Safari 14 version is: Version 14.0.2 (16610.3.7.1.9)
The error persists with Safari Technology Preview (Release 118 (Safari 14.1, WebKit 16611.1.9.3.1)) also.

Thanks for any insight!
