Installed the following packages & versions (latest versions) into a Foundation site:
Cause and Solution
The interface ICacheService has been removed in EPiServer.ConnectForMarketingAutomation 5.7.0. Ideally, the version should have been made 6.0.0. If any methods in this interface are being used in ConnectForCampaign, they should be replaced by the methods in ICacheHelper.
Short-term fix: The highest version of ConnectForMarketingAutomation should be made 5.6.3 in the dependencies of ConnectForCampaign.
