If something becomes a copy of Protean Thaumaturge, it also has the constellation ability.
2020-01-24
A constellation ability triggers whenever an enchantment enters the battlefield under your control for any reason. Enchantments with other card types, such as enchantment creatures, will also cause constellation abilities to trigger.

Protean Thaumaturge’s ability causes it to become a copy indefinitely. It doesn’t expire during the cleanup step or if the target creature leaves the battlefield after the ability has resolved.
2020-01-24
An Aura spell that has an illegal target when it tries to resolve doesn’t resolve and is instead put into its owner’s graveyard. It doesn’t enter the battlefield, so constellation abilities don’t trigger.
