I've got a game that I can deploy to xbox but can't run locally on the PC. Until a couple days ago, this worked. I get this problem for VM or YYC. This is after the build, on the deployment. X:/bin\dpdeploy.exe -s -c "C:\Users\jonpu\AppData\Local\Temp\dpdeploy-container-ac128552abcda8258e58150177600912" -h=localhost:50443 -u=jon_gms -p=xxxx list-apps System.Exception: unable to install app on device at Igor.WinUWPBuilder.DoInstall(String packageFullName, String appx_path, String certificate_path) at Igor.WinUWPBuilder.BuildWindowsUAPProject(String package_name, String _targetfile, Boolean _final) at Igor.WinUWPBuilder.Run() Igor complete. IDE 184.108.40.2063 Runtime 220.127.116.118 Windows SDK 10.0.17763.0 Today I switched to the real MS Store cert for the game, but that made no difference in this problem. Again, I can build for submission to the store and I can deploy to xbox. Pulling my hair out on this. HELP!!!!
