Hey yall! Our team and I are running into a bit of an issue We’re trying to export a build of a game that uses unreal 5.7.4 with the fmod plugin but it doesn’t seem to work

The game and audio runs fine in editor but when trying to export a build we get the following error message:

Here is a screenshot showing our Plugin version 2.03.14

Any help would be greatly appreciated. Thanks in advance!

This looks like a known issue with Blueprint-only projects. Is your project a Blueprint-only project?

If so, could you please try following our [Unreal Integration | Troubleshooting - Blueprint only projects](https://fmod.com/docs/2.02/unreal/troubleshooting.html#blueprint-only-projects) to add a C++ class to the project and see if that resolves the issue?
