Line 74. Replace : "#like-button > ytd-like-button-renderer" with : "#top-level-buttons-computed > ytd-segmented-like-dislike-button-renderer"

Line 106. Replace return getButtons().children[1]; with return getButtons().querySelector("#segmented-dislike-button");

Line 112. Replace getDislikeButton().getElementsByTagName("yt-formatted-string")[0] with getDislikeButton().querySelector("ytd-toggle-button-renderer > yt-button-shape > button > yt-touch-feedback-shape")

Yes, my fault. I did editing again and now it works. Thank you.

I have something to add. If in your browser the dislike text is wider than the dislike button, add the following line after the mentioned new line 274:
#segmented-dislike-button button {width: unset;}

One more issue: when you click dislike button, the number of dislikes dissapears. In order to make it fully functional again, one should do more editing:

Line 611.
Replace buttons.children[1].addEventListener("click", dislikeClicked);
with buttons.querySelector("#segmented-dislike-button").addEventListener("click", dislikeClicked);

Line 613.
Replace buttons.children[1].addEventListener("touchstart", dislikeClicked);
with buttons.querySelector("#segmented-dislike-button").addEventListener("touchstart", dislikeClicked);
