IOS remote package fails in 4.21 - System.IO.FileNotFoundException

Until 4.20 i could do a remote package for IOS without problems. With 4.21 i am getting this System.IO.FileNotFoundException:

ERROR: System.IO.FileNotFoundException: Could not load file or assembly 'System.ServiceProcess, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Does anyone have remote package working on 4.21?

I have tested with the release branch and the 4.21 branch (d1206c126c45116997795609bd3951ba51ebdce5) and got the same error. The remote is a macos high sierra (10.13.6) with xcode 9.4.1




Finally got it working after running Engine\Binaries\DotNET\GitDependencies.exe --all

For some projects i had to change the default BundleIdentifier= in UnrealEngine\Engine\Config\BaseEngine.ini () too because the project setting was not being used.
