Doesn't work on certain facebook videos when audio setting is enabled

[LatinSuD]

Example:
https://www.facebook.com/reel/420174524346370

Error message is:

Uncaught TypeError: Cannot read properties of undefined (reading 'div')
    at eval (eval at runAction (inject.js:771:13), <anonymous>:1:41)
    at Array.forEach (<anonymous>)
    at eval (eval at runAction (inject.js:771:13), <anonymous>:1:11)
    at runAction (inject.js:771:13)
    at HTMLDocument.<anonymous> (inject.js:611:11)

The problem is at line 771:

mediaTags.forEach(function (v) {
    var controller = v.vsc.div; 
    ...

In my case it was produce because of an AUDIO tag did not have a "vsc" attribute.
If I disable the "work on audio" extension option it works.

You could check for the attributes or simply use a try/catch block.
