Importing Unity integration package does nothing and breaks my project

[A-NaCl]

After installing the FMOD unity integration package, I’ve received multiple errors, and it always breaks my Unity project, making it unplayable.
I receive the following errors:

Additionnally, importing the package never adds the FMOD tab to my Unity Editor. This happens in all of my projects, and I’m not sure where the problem is originating from. This is my first time using FMOD or any similar software, and it is distressing as I can’t even get the first step working, so any help would be greatly appreciated.

From my experience this usually happens when there are other script errors that will break the compilation process. Check the console if there is anything besides FMOD giving an error and fix that. In this specific case it seems that maybe the Timeline package isn’t installed. Check in the Package Manager Window if the Timeline package is installed and if not, install it.
