Added Exception Handling for Out-of_Bounds Tab Index Selection

[IllianiCBT]

• Encapsulated tab index selection logic in a try-catch block to prevent crashes when the index is out of bounds.
• Ignored exceptions as the default behavior safely skips selection if the index is invalid.
• Added a comment to clarify this behavior.

Fix #5751
