What happened?

Every time I open youtube I get this error:

[Magic Userscript+] (make) Failed to set the 'innerHTML' property on 'Element': This document requires 'TrustedHTML' assignment.

It just started happening about an hour ago.

Steps To Reproduce

1. Have Magic Userscript+ : Show Site All UserJS enabled in tampermonkey
2. Open youtube

I see the problem, I will fix this in the next update

Fixed as of v7.1.1, the Trusted Types API is the issue.

The trustedTypes.createPolicy() function is already added to the script to bypass this, however it looks like on youtube.com with the Brave browser it needs to be injected sooner.

window.trustedTypes.createPolicy('default', {
  createHTML: (string) => string
});

If this does not fix your issue create a new issue along with any additional UserScripts or WebExtensions you have installed for youtube.
