Script error on start in Universal only

Product: PowerShell Universal
Version: 1.5.6

Starting a script in Automation and get this error below but not when I run the same script in powershell normally? this error shows in the output tab but not when you view the errors tab.

Failed to verify module and server version. Could not load file or assembly ‘System.Text.Encoding.CodePages, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The system cannot find the file specified.

This has been resolved in 1.5.7.
