There was an update by uBlock in the resources file, which Brave uses to Inject JS to block ads and different things on the internet, what makes Brave an advanced native adblocker.
Since it broke Brave (but doesn’t affect uBlock) then it is a general problem for Brave users, the problem was already reported, and Brave Browser will get an update soon, to fix the Brave Ad Block Resources Library
This is what is breaking everything this line of code function () {} which causes every other scriptlet to fail, not just the scriptlets that have it but others as well if used in the same website.
There is nothing you can do, unless you waste your time manually removing the problem. It is just an empty function that is causing all the issues since it is taking down any injected JS that might work with it.
So, tomorrow it will work fine again.
