Failed to run serialization weaver (Win 8.1)

Chaos

Hi Guys,

I just recently updated PUN and Photon voice to the latest version in order to add voice support for my UWP 8.1 game. Before I updated (Voice v1.0, PUN v1.66), the voice chat was working in the editor only. When I was deploying in VS it gave me an error that it did not find opus_egpv.dll and now when I updated to the latest version it gives me the following long error when I start building inside Unity:

UnityException: Failed to run serialization weaver with command "Temp\StagingArea\Apollo X Companion App.Windows\Data\Managed\Assembly-CSharp-firstpass.dll" -pdb -verbose -unity-engine="Temp\StagingArea\Apollo X Companion App.Windows\Data\Managed\UnityEngine.dll" "Temp\StagingArea\Apollo X Companion App.Windows\TempSerializationWeaver" -additionalAssemblyPath="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETCore\v4.5.1".

I am using Unity 5.3.4p1, PUN v1.67 and Voice v1.2. Build target is "Universal 8.1". Is there any workaround for this?

Something I noticed is that when I updated Voice alone the error above did not appear but another error appeared in Visual Studio which caused the game not to start at all. Once I updated PUN the error started appearing. I hope that helps determining the problem.

EDIT: So after several retries, I updated to Unity 5.3.4p5 and found out that the error does not appear anymore (even though I updated and reverted back before, so no idea why it is gone now). Now though, voice chat does not work when exporting to Universal 8.1. It does not find opus_egpv.dll. When exporting to Universal 10 it works as expected. Problem is though I want to use Universal 8.1 as for some reason exporting to Universal 10 makes the game's performance drop in contrary to Universal 8.1.
