Hello,

However for technical reasons I had to update my version of unity (from 2020.3.21 to 2021.2.21) and now I have a problem. I can’t build with the fmod nintendo switch package. I have checked that this is where the problem comes from because when I delete completely fmod, the build succesed.

I specify that I have the last version of fmod up to date and i have the nintendo switch sdk for unity 2021.3.21.

I join the errors that are displayed in the console.
