I found this [0] that the logic followed is a citizenship generally has to be voluntarily resigned but several actions can make you "accidentally voluntarily resign" it so to speak. It's strange to me Biden would do this especially since we aren't in open war with China but every day I wake up this world gets more strange. It does suggest certain crimes must be done with the intent to lose your citizenship as you suggest which makes Biden's action even more dangerous.
