Missing Library/Audio/Plug-Ins/HAL

My audio stopped working after installing the Mojave software update many weeks back and at the time when my audio stopped working, I tried some simple troubleshooting but nothing worked. Now I'm seriously trying to fix this issue and a fix that many people did was going to Library/Audio/Plug-Ins/HAL and deleting the InstantOn.driver. When I go to Library/Audio/Plug-Ins, there is only a Components folder, a digidesign folder, and a VST folder. All the folders are empty, in-fact, all audio folders are empty. Does anyone know how I can install the plug-in HAL so I can fix my audio or how I can fix my audio in-general?

Answers will be greatly appreciated :)

Do you have or know of another Mac that is running Mojave, you could copy the contents of theLibrary/Audio/Plug-ins folder over to your Mac. Restart it and see if your audio now works.

Try downloading the Combo update and then installing it, it may resurrect your audio.

If all else fails redownload the full Mojave installer and install over what you have got.
