APNG's are not working

https://8f42856c.avrig.pages.dev/ The APNG files simply do not render, and visiting their URL shows a broken image/result. The other images (jpg/png) work fine. Is cloudflare doing some weird mutations/changes to my images which causes them to break? The images work fine locally, or when deploying the build folder manually to a new cloudflare pages application - as seen here: https://avr-demo.pages.dev/assets/system-24888369.apng
