Hi Jeff, I have cleared the files from the path \AppData\Roaming\OpenSpan, Still I am getting the same error.

I have updated only Two xml files with the valid entries . One is RuntimeConfig.xml and another one is StudioConfig.xml. See the below and let me know if there is anything needs to be updated apart from these two files. Thank you.!

RuntimeConfig :

<Robotics>
        <!-- PegaServer tag is specific to RPA. -->
        <!--   baseurl: Base address for Runtime to use for calls to request work items.-->
        <PegaServer  baseUrl= "http://localhost:8080/prweb/api/v1/" />
        <!-- LocalApiService tag is specific to RDA. -->
        <!--   enabled: If true, the Runtime will self host a REST service to accept requests from the Pega application. -->
        <!--   SSL: If true, the service uses SSL and must be accessed via https. -->
        <!--   port: Port the service will listen on. -->
        <!--   allowedOrigins: Comma delimited list of domains that the service will accept requests from. -->
        <!--          A specific domain can be given (i.e. acme.pega.com) or the subdomain may be wildcarded (i.e. *.pega.com) -->
        <!--          Requests from any domain not in this list will be rejected. -->
        <LocalApiService enabled="true" SSL="true" port="9443" allowedOrigins="*.pega.com"/>
    </Robotics>
  

StudioConfig :

<Robotics>
        <!-- baseUrl: Address of Pega API endpoint -->
        <PegaServer baseUrl="http://localhost:8080/prweb/api/v1/"/>
        <!-- The following credentials allow Studio to authenticate with the Pega server. -->
        <!-- This user has read only access Pega class and field names. -->
        <!-- No other permissions are required by or granted to this user. -->
        <!-- userName: User name used to authenticate with Pega server. -->
        <!-- password: Password used to authenticate with Pega server. -->
        <RDA_Credentials userName="CASysAdmin" password="install"/>
    </Robotics>
