I don't foresee a problem here, your MEX is due to arrive at 16:40 (T5) and your CDG departs at 18:10 (T5). 90 Minutes is plenty of time to make the connection.
If you do misconnect (and there is no one waiting for you at the end of the jetty, look out for the purple jackets) update your App to see if you have been rebooked and if not head to flight connections and the customer service desk where they will sort you out. If you cannot be accommodated that day they should organise a hotel for you too (or advise how to reclaim the cost if organising yourself),
