Hi @ItsLucky 2490 ,
I can replicate this issue here. I have tried allowing autoplay at edge://settings/content/mediaAutoplay (You may have a check, too), but it seems to have no effect. I suggest sending feedback to the Dev Team by pressing Alt+Shift+I in Microsoft Edge to report this issue.
As additional information, I don't think it is related to Microsoft Edge itself, but it is more likely to be an ntp.msn.com website issue. I tested on Edge 113, which was a release of 2 months ago, and I could still replicate this issue. But you can still send feedback inside Microsoft Edge.
