Unity3D2018.3版本打包UWP遇到IOException: Win32 IO return

Posted 2020-12-13

Unity3D2018.3版本不是很稳定，在需要Target SDK Version为10.0.17134和10.0.17763版本时，打包UWP会遇到

IOException: Win32 IO returned 234. Path: C:Program Files (x86)Windows Kits10References10.0.17763.0Windows.ApplicationModel.CommunicationBlocking.CommunicationBlockingContract2.0.0.0Windows.ApplicationModel.CommunicationBlocking.CommunicationBlockingContract.winmd" or "TempStagingAreaDataManagedWindows.ApplicationModel.CommunicationBlocking.CommunicationBlockingContract.winmd

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

的问题，大致就是Unity在打包UWP时需要从windows 10SDK中复制一个文件失败，导致缺失。

上谷歌搜了一下，有一种解决办法就是升级一个小版本在进行打包，有些好使，有些不好使，还有说是需要的那个文件名字太长不能识别。

在这种情况下，我将

C:Program Files (x86)Windows Kits10References10.0.17134.0Windows.ApplicationModel.CommunicationBlocking.CommunicationBlockingContract2.0.0.0

中的文件删掉，从新打包，很完美的就打包出来了，是没错误的。
