Wait for the preliminary report
Your question can be answered by an official source after the preliminary investigation report is published or by the airline itself. We will never know the MEL items open on that aircraft unless you have access to the Airplane Technical Log for VT-AXH or the airline engineering/technical department.
For any failures in-flight, it hasn’t been reported as yet if the pilots informed ATC or their ground operations about any technical issues affecting their approach & landing capabilities.
