The “Lookup failed for ParameterLayoutModel” messages indicate that your project is unable to locate missing parameter sheets, possibly because those sheets have been removed from your project’s events, but some references to them remain due to an incorrect merge or other source control-related error.
Have you tried selecting “File > Validate Project…” to automatically detect and fix issues of this type?
Unfortunately, without access to your project, there is no way for us to precisely identify and fix the cause of this issue. If you want, you can upload your project on your profile page on the FMOD Studio website.
That being said, if your project isn’t exhibiting any strange behavior when tested in FMOD Studio or in your game, it’s likely this error is benign. I therefore do not recommend recreating your project from scratch unless you discover your game’s audio is affected.
