Explanation:

When a UI element selector changes, it can break automation. The proper debugging sequence ensures an effective fix while preventing future failures.
Step 1: Examine Error Logs
# First, review error logs in the Output Panel to locate the failing activity.
* This helps determine which selector is causing the issue.
* Use UiPath's Exception Details to pinpoint the problem.
Step 2: Verify Selector and Insert Breakpoint
# Open UI Explorer to inspect the failing selector.
* Compare the new selector vs. old selector.
* Use a Breakpoint at the failing activity to analyze execution in Debug Mode.
Step 3: Modify Selector for Flexibility
# Adjust the selector to make it more resilient by:
* Using Wildcards (*) for dynamic attributes.
* Implementing Anchor-based selectors.
* Utilizing Modern UI Automation if applicable.
Step 4: Execute in Debug Mode
# Run the automation in Debug Mode to verify that:
* The updated selector correctly identifies the UI element.
* No further exceptions occur during runtime.
