I have recently been working on a project and the integration set up was working, however it is now coming up with these issues. I am wary about attempting to remove the integration from FMOD as I do not want to mess up the files. I’ve also tried to import an fmod unity integration package 2.0110 which matches fmod’s version. Any help on this would be greatly appreciated!
