Page download failing for Youtube when using browser cookie about single-file-cli

[Spicadox]

I guess not, unless you're willing to use my cookie file, then I could dm you my cookie file.

After looking into it more, I found that my script file may also be contributing to the issue. I may be grasping at straws and since you haven't reproduced the issue you probably won't know, but my script basically ensures the image quality is at the highest plus with cookies there would be more images and content populating the page. As such, for a huge webpage with lots of images, I'm guessing this could cause an issue since removing either my cookies or script in the command(so either less data being saved or a very large image is perhaps causing issue) won't result in the error?

edit: Manually running each part of my script on chrome and then using the single file extension seems to work though so I'm at a lost

edit2: Sorry for being a pain but setting images to a smaller size of max height of 720 fixed the issue so I am guessing large image(s) is causing issue with base64 string being too large?

Script in question(not great with javascript, but it's been doing it's job fine on other smaller pages):

// ==UserScript==
// @name         Change images' resolution
// @version      1.0
// @description  [SingleFile] Replace img url with a higher resolution version
// ==/UserScript==

    // Get the image element that has a src attribute and an empty alt(use to ignore profile images)
    const imgElementsSelector = "img[src]:not([src=''])";

    // Regex grouping[0] is the original string
    // Group[1] is the entire string before =s where everything after the domain name is between 30-85 characters
    // Group[2] will be used and set to 0 to obtain the max resolution of the image

Is it possible for me to reproduce the issue?
