Due to compelling national interest, for the survival of the military regime, and for the prosperity and security of its governing elite, Egypt is a status quo power. They are therefore deeply hostile to Hamas and other Muslim radicals and terrorists and are de facto allies of Israel against them. Egypt is thus content to let Israel destroy Hamas.

Over and above that, Egypt *just* got rid of the *extremely* detested Muslim Brotherhood that were running their country for a while. They absolutely *hate* people like that now, and have since been extremely hostile to Hamas even before the war. The “status quo” thing went away when the Brotherhood took over for a few years.
