Embedded Youtube Videos Disappeared After Update

My old embedded youtube videos are no longer showing and I just noticed after series of updates. Although I tried adding a video again using the Youtube url on the Video Post Format and it worked but doing this for all my video posts all over again will be extremely frustrating and tiring as I have hundred of videos already embedded (I operate an entertainment blog).

Old video post – https://www.debarayonline.com/video-future-my-savages/ (no more video)

Recently updated video post – https://www.debarayonline.com/video-beyonce-ft-blue-ivy-blue/ (works fine).

Please how can I resolve this issue and get all the videos showing again without having to re-embed one by one.
