Thanks for reporting this, and sorry about the issue. We recently added stricter YouTube 18+ filtering, and it looks like some normal videos/channels are being incorrectly detected and blocked. I’m currently working on improving the detection logic to reduce false positives like this.

For now, you can temporarily disable the YouTube 18+ filtering feature in the extension settings page while I work on a fix.

Your feedback really helps since it lets me identify cases that slip through testing. Thanks again for taking the time to report it.
