Hi, I've had a working project under Unity 2018.1 PC build fine, so I ported it over to a UWP project as I'm using an Acer headset from the Microsoft Mixed Reality Developer Program. It would not build initially as it threw up many errors with different asset store packages that were fine under PC build. So I fixed all them. Finally it started to build. Crashed my machine at one point recompiling shaders (it hit 80 degrees C on a Ryzen 7 1700 OC'd to 3.8ghz). Finally, it seemed to be going through and then right at the very end... UnityException: Failed to run serialization weaver with command "-pdb" "-verbose" "-unity-engine=Temp\StagingArea\Data\Managed\UnityEngine.CoreModule.dll" "Temp\StagingArea\TempSerializationWeaver" "-lock=UWP\project.lock.json" "@C:\Users\paul\AppData\Local\Temp\tmp277914ae.tmp" "-additionalAssemblyPath=Temp\StagingArea\Data\Managed". *sigh* tired of fighting this UWP. Any clues? ty!
