Hi, had today the same experience. 5 CTD`s during content manager updates, 1 in the map view and another one when seated in an airplane at the apron.
Community folder renamed and navigraph navdata center removed before sim update.
Found a topic here on the forum where it is stated that navigraph users should remove the app and the data before updating and at least start the sim once before reinstalling navigraph
However have not done longer flights yet
