Dynamics Connector Client Fails to Open after upgrade to RU3

Hi,

I have upgraded our Connector UAT environment to the latest connector release RU3 to test the upgrade process. The installation completed without any errors but now when opening the client an Object reference error is thrown and the client closes.

Has anyone else experienced this problem?

Connector client error:

Details from trace file seem to indicate it’s a problem with loading the employee map from the objectprovider file?

Trace log:
