Hello,

When i build a copy of my game to my phone, I get the error,

Error building Player: Exception: Failed to run serialization weaver with command line “Temp/StagingArea/Data/Managed\Assembly-CSharp-firstpass.dll” -pdb -verbose -unity-engine=Temp/StagingArea/Data/Managed/UnityEngine.dll “Temp/StagingArea/TempSerializationWeaver”.[Temp/StagingArea/Data/Managed\Assembly-CSharp-firstpass.dll]
Symbols will be read from Temp/StagingArea/Data/Managed/UnityEngine.pdb
System.InvalidOperationException: Operation is not valid due to the current state of the object.

at Mono.Cecil.ModuleDefinition.ReadModule(String fileName, ReaderParameters parameters)
at usw.Weaver.Weave()
at usw.Program.RunProgram(ConversionOptions options)

I have successfully built games on my phone before, but now it will not work for any project.

Any help would be great,

Try switching to a different build target (desktop, or web, or etc), doing a build, and then returning to the WP8 build target.

I managed to fix a similar build stop error which I encountered on 4.5.3f3 building for Windows 8 Store.

My issues was that I had to update code to not use incompatible interfaces with the Windows Store. With the removal from our code of the 3 unsupported Windows Phone and Windows 8 interfaces, the problem was completely eliminated. So I would recommend building with “Use Net Core” and double checking that you are only using compatible interfaces with the Windows Store/Windows Phone frameworks.
