Yes, that’s called a slave revolt. In that specific case, a couple things of note:
1: You can have both slaves and “free” workers build the same thing.
2: Egypt almost certainly enslaved a large number of war captives from the Sea People invasion
3: That is literally five hundred years after the last pyramid. The Pharaohs moved on to building hidden tombs because it was both cheaper and less of a giant stone monument telling thieves were a rich guy buried some treasure.
