Hello,
I’m having an issue when trying to build a project on my iPad. I am getting an error because of fmod, looking like this:

I am using Unity 2019.4.4f1, xcode 13.1, MacOS 12.0.1 (monterey), and fmod 2.00.07. Any ideas why this is happening, or how can we fix it? I’d appreciate any kind of help, i really have no idea how to fix this and get the build working…

Sounds like the same issue as described here, except I’m guessing you haven’t modified your XCode project at all?
I have not been able to reproduce this error with your version, can you tell me a little more about your project? Are you using custom plugins, or anything like that?
