fix: handle exceptions in xmr data logging

Added a try-except block when printing XMR-related data to handle potential exceptions such as missing social data or uninitialized variables. This prevents the application from crashing due to `Social.DoesNotExist` or `UnboundLocalError`, enhancing robustness and ensuring smoother operation.
