I believe there had been a temporary error. I have checked in 3 different devices after reading your question but I confirm that the videos are playing fine on all the devices. We are using the latest Edge browser,
Version 116.0.1938.76 (Official build) (64-bit)
So, kindly double check by clearing your browser cache. In case the issue remains, try disabling any browser add-ons you have installed and also restoring to the factory settings.
Hope this solved your issue!
