The "comment" keyword in the code makes the next code color the same as the actual comment color.

The code color becomes the same as the actual comment's code color after using the "comment" keyword.

This seems to come from a conflict with a different plugin because I'm not getting this.

You'll see it also doesn't do it in GitHub (which uses the same syntax highlighting grammar):

<div>
  {% comment %}
    this is a comment
  {% endcomment %}

  <p>lorem ipsum</p>
  {% assign comment = 10 %}
  <p>{{ comment }}</p>
</div>

@MubeenMurj you may have the Liquid extension called "Liquid" by Panoply installed 👀 ...
