After an AppAssure core upgrade the UI fails to open and the following error is received.
"System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: The method can be called only on a type for which Type.IsGenericParameter is true. to System.RuntimeType.get_DeclaringMethod ()"
One or more protected agents are running on older builds
Upgrade all agents to match the build of the AppAssure Core.
Run a repair of the Core.
