Hello Shahaji,
If there is configuration management solution in place for these Runtime Resources, one of the first things to check is to see if something has been deployed to this production VM. Software distributions to this system (patch? specific software upgrade) may affect the behavior of local applications. If the application being automated is a SaaS or internally hosted application, it would be good to check if there has been updates. These could impact identifying and interacting with elements in AA (and other) modes.
