I’m having issues with getting FMOD to run in UE5.1. I did several reinstalls, added it to blank projects, imported the data, … at some point it always stops working. And the main issue seems to be a Json failure. I get variations of this text:

```auto
Failed to read file. Invalid Json Token. Line: 1 Ch: 1
…/Project/Plugins/FMODStudio/._FMODStudio.uplugin

```

The thing is, I was able to get the engine to recognize the plugin in some cases, so that it plays in engine. But as soon as I try to package the game I get this error message. I’m working mainly on a Mac with the latest OS installed. I also tried to switch to windows, but the issue remains. Here the error often is displayed from the get go, so that I can’t open the project at all (I tried FMOD2.02.11 for Win and Mac respectively).

Any help here would be appreciated.

Hi,

Could you please post the contents of your `FMODStudio.uplugin`? Can you also confirm the filename of the `FMODStudio.uplugin` file?

I left the plugin unchanged. So the original name is “FMODStudio.uplugin”. The plugin name that causes trouble is not visible in the regular file browser. I was able to see it when I opened the folder in Xcode/Visual Studio, but couldn’t access it afaik.

```auto
{
    "FileVersion" : 3,
	
	"FriendlyName" : "FMOD Studio Integration",
	"Version" : 20211,
	"VersionName" : "2.02.11",
	"CreatedBy" : "Firelight Technologies",
	"CreatedByURL" : "http://fmod.com",
	"Description" : "FMOD Studio Integration.",
	"Category" : "Audio",
	"EnabledByDefault" : true,

	"Modules": [

	],

It sounds like you might be running into the same issue as this user: [Packaging for Mac - JSON Parse Exception FMODStudio.uplugin - #3 by jmccormicksae](https://qa.fmod.com/t/packaging-for-mac-json-parse-exception-fmodstudio-uplugin/19214/3).

Could you try cleaning up any hidden files containing the `._` in their paths that might be causing issues?
