Hi,
I tried following the steps in the video you shared, but I wasn’t able to reproduce the same issue. I'm wondering if it is a cache problem. You can try deleting the new tab page cache and see if it helps. Close all the new tab page then navigate to Edge Settings > Privacy, search, and services > Cookies > See all cookies and site data. Search for ntp.msn.com (should be under MSN) then delete it to see if it works.
If it doesn't work, go to Edge Settings > System and performance > System > Toggle off Use graphics acceleration when available. Restart the browser then check again.
