Asking current and experienced 320 family pilots.
What you do in this situation? I take it there's no actual procedure for this type of event, but curious as to what approach you pro pilots would take. Just throwing a few things in there as questions.
Stabilize, assess, check lists, look at ECAM for failures/warnings , speak to your tech people, send your FO back to have a look?
Deploy slat/flaps and risk further unknown effects or land flaps up?
