Random broken images

Hello.

I've done all the preliminary steps of updating GP, disabling caching, turning off plugins, etc.

For some reason, I am having certain images break specifically on desktop Safari browser on Mac. Running Safari 13.1.2 on Catalina 10.15.6.

Page with two broken images (one on top and one on bottom): https://comfyweightloss.com/start-here/

It's weird, because the Safari browser on mobile shows the images perfectly. Other browsers like Chrome (mobile or desktop) also have no issues.

I've tried taking one of the broken images and replacing it with a new version (for example, old version was a PNG and replaced with a new JPEG) but that didn't work.

Thanks for your help.
