If an effect causes Bello to lose all abilities during your turn, its effect will still apply to non-Equipment artifacts and non-Aura enchantments you control.

Any counters that are put on an artifact or enchantment while it's a creature because of Bello's ability remain on that artifact or enchantment while it's not a creature, even if they have no effect on a noncreature permanent.

If an Equipment becomes attached to an artifact or enchantment that's currently a creature because of Bello's ability, it'll become unattached during the next upkeep that isn't yours. Similarly, any Auras that become attached to those artifacts or enchantments that can't enchant the appropriate permanent type will be put into their owners' graveyards.
