Issue
After installing a Fix Pack, when attempting to login to the K2 site, you see the following error:

Error Code
The type initializer for ‘SourceCode.Security.Claims.Sts.Shared.Authenticate’ threw an exception
Resolution
From the InstallerTrace log, it was determined that some of the controlpack controls were not registered successfully due to a timeout reached when attempting to start the K2 service.
StartService.TestHostServerConnection: Connection to host server timed out. Increase the 'validationtimeout' setting in the product config to increase the time out Logged Error: Target did not complete successfully: Register_Control_Choice Logged Error: Target did not complete successfully: Register_Control_HTMLEditor Logged Error: Target did not complete successfully: Register_Control_ListBox Logged Error: Target did not complete successfully: Register_Control_Tree Logged Error: Target did not complete successfully: Register_Control_WorkspaceControlPack Logged Error: Target did not complete successfully: Register_Control_WorkspaceControlPack_F74DN Logged Error: Target did not complete successfully: ClearControlCache
Re-installing the same Fix Pack resolved the issue.
