How did the death of Louis-Philippe's son Ferdinand in 1842 weaken the July Monarchy?

The death of Ferdinand, duc d’Orléans, in a carriage accident in July 1842, was a significant blow to the July Monarchy. Ferdinand was the popular heir to the throne, and his sudden passing at the age of 31 deeply grieved Louis-Philippe and left the dynasty in a precarious position.12

The tragedy weakened the regime because it necessitated the prearrangement of a regency for the new heir, Philippe d’Orléans, comte de Paris, who was only an infant at the time. By removing the adult successor who provided stability and continuity to the crown, the accident undermined the long-term security of the Orléanist monarchy, leaving it vulnerable to the political instability that eventually contributed to its collapse during the February Revolution in 1848.13
