ERR_INVALID_HANDLE returned after each EventInstance release

Every time I either play a sound using FMODUnity.RuntimeManager.PlayOneShot or release any EventInstance manually, I’m greeted by an error from FMOD.
Here’s the log in more detail:

[FMOD] EventInstance::getPlaybackState(000000D96B9DE298) returned ERR_INVALID_HANDLE for STUDIO_EVENTINSTANCE (0x2024A0).
UnityEngine.Debug:LogError (object)
FMODUnity.RuntimeManager:ERROR_CALLBACK (intptr,FMOD.SYSTEM_CALLBACK_TYPE,intptr,intptr,intptr) (at Assets/Plugins/FMOD/src/Runtime/RuntimeManager.cs:63)
FMOD.Studio.EventInstance:getPlaybackState (FMOD.Studio.PLAYBACK_STATE&) (at Assets/Plugins/FMOD/src/Runtime/wrapper/fmod_studio.cs:1235)
FMODUnity.RuntimeManager:Update () (at Assets/Plugins/FMOD/src/Runtime/RuntimeManager.cs:477)

Help :sob:

Can you please tell me what version of FMOD you are using, and share a code snippet of how you are calling FMODUnity.RuntimeManager.PlayOneShot and release?
