I’m seeing the following error spammed on two projects when built for PS4:

```auto

```

One project is on 2019.4.7 and the other is on 2019.4.12, but both projects are using the current latest Unity verified version of 2.00.10. I’ve confirmed that both projects have the FMOD PS4 plugin installed, both libfmod.prx and libfmodL.prx exist in the project, and plugins correctly have their platform settings configured.

This is a blocker for these projects and would love to have a solution 🙂 If this isn’t the appropriate channel, can someone direct me to a better one? I’ve just noticed today that there is a [PS4 category](https://qa.fmod.com/c/ps4/12) but I don’t seem to have access to it.

It appears that this is caused by an SDK mismatch, if you require FMOD built for a different SDK version you can send an email to [support@fmod.com](mailto:support@fmod.com).
