4.27 Fmod 2.02.03 : Attempted to create a package with name containing double slashes

Hello everyone!

We have upgraded our UE project to 4.27 and fmod plugin from 2.02.00 to 2.02.03.
After we packaged a build and try to run the game, we get a crash indicating a wrong path where “/Game/” is added to our ‘ContentBrowserPrefix’ setting in the project/plugin settings.

Our FMOD defaultEngine.ini
Bank Output Directory: FMOD
Content Browser Prefix: /Game/FMOD/

Our Packaging project settings:
Additional Asset Directories to Cook:
/Game/FMOD/Banks
/Game/FMOD/Buses
/Game/FMOD/Events
/Game/FMOD/Reverbs
/Game/FMOD/Snapshots
/Game/FMOD/VCAs
/Game/FMOD/PrivateIntegrationData
Non-Asset Directories To Copy:
FMOD/Desktop

I tried builds with and without the “/Game/FMOD/PrivateIntegrationData” but it doesn’t help. Also removing the /Game/ does not work and always requires it.

Unfortunately there was an issue with our 2.02.03 release for Unreal. We’ve already fixed it and put up a patched version. Please download the fixed version (it has the “patch1” designator).

You may need to delete the content browser prefix line out of your DefaultEngine.ini and delete /Game/FMOD/PrivateIntegrationData from your Additional Asset Directories to cook.
