Good evening
I’ve managed to integrate the Vivox Plugin into my project. Everything works ok in editor but when I package the project into a windows 64/86 application I get a “Fatal Error!” windows.
I spent the whole day trying to figure out what it is but I can’t. Logs show the following error:
Fatal error!

I don’t understand why it’s trying to read anything from d:/agent/… since I don’t even have that drive.
I googled this specific problem and i found it associated with a Magic Leap issue found here Unreal Engine Issues and Bug Tracker (UE-69422) but disabling magic leap and all other vr/ar plugins didn’t help at all.
Anyone have any ideia what might be happening?
[EDIT]
The post with the error about magic leap made me look into other possible plugins that might be causing the problem. So I desabled them all. Except the ones i really needed and still the porblem persisted. But then I found I had two vivox plugins. The one I added as per vivox recomendations and a build-in one. When I disabled the built in one the error stoped happening 
It was a tiresome day but I’m happy to have solved this. Thank you.
