Unable to open Explore Data

In Pega Constellation, while opening Explore Data, I am getting the following error. How can I resolve this issue?

Error:

Unable to open an instance using the given inputs: pxObjClass = "Rule-UI-RemoteInfo", pyRuleName = "RemoteCaseTypesMapping"

The error usually indicates that Pega is trying to load a Remote Case Types configuration (Rule-UI-RemoteInfo → RemoteCaseTypesMapping) that is missing, inaccessible, or corrupted. First verify whether the RemoteCaseTypesMapping instance exists

Class: Rule-UI-RemoteInfo
Rule: RemoteCaseTypesMapping

Are you seeing this in Tracer? Or are you getting the error on screen? I have seen this multiple times in Tracer but it immediately gets cleared by next steps. I believe there is a different issue.

I am seeing this on the tracer while opening of Explore data from App studio..
