I surveyed Brave Community forum as well as subreddit and GitHub issues to see how often issue repeats itself. Here’s what I found.

No solution apart from creating a new profile.
Youtube comments are not loaded
No solution apart from creating a new profile.
Youtube comments section freezes after like on mobile
No solution
Youtube Comments Not Working
No solution

Cannot Comment on YouTube
No solution
YouTube comments not loading
No solution. Some hacks like signing into YouTube with a Google account, watching a video, and then signing out seem to have to have worked for somebody. Nothing real.
Brave not loading youtube comments.
No solution apart from hacky log in/log out.
Ad block is blocking youtube comments
No solution. Private window workaround was offered. At least in my case, Private window will also get “clogged up” just like a normal profile.
In my Brave the Youtube comments are not loading
No solution
Brave issue with Youtube
Solution: Google Translate extension causing the issue was accepted as resolution despite evidence that the issue persist in a stock browser with no extensions.
Problems about using Brave’s adblocker on YouTube
Solution: OP was experiencing the issue while also having Cookies blocked completely. Setting cookies to Block 3rd party cookies or Allow All Cookies was accepted as resolution, which it doesn’t seem to be based on several other threads including this one.
Youtube comments not loading
Solution: “Clearing all the cache and cookies” was accepted as resolution here. I can see how only clearing cache and cookies for youtube.com domain would pass for resolution, however the issue seems to require removing all site data.
