We have a 5 month old at home. I work when I can
The colour space was Adobe Pro RGB in the JPEG you sent me. We convert JPEGs to WebP if the browser you're using supports it as these are smaller files, usually without any quality loss, and saves us bandwidth and enable the photos to load faster. I think this is where the problem arose though. I'm not sure it liked the Adobe Pro RGB colour space.
If you save it using sRGB it should be good in the future. Photoshop Elements should support this.
I converted the image you sent me to sRGB and replaced the image from your upload:
