I think you should open support ticket and add some extra informations. This error is on browser or DT? It's right after start recording or during some particular user action etc.

Hey Manohar,

The provided error can occur when the agent deactivates itself and does not properly deactivate the auto-instrumented part of the app. The problem was solved in version 8.231.2.1007. Please rebuild your Android app with an updated agent version.
