In Rogue One,
The Imperial Security Complex is destroyed by an indirect blast from the Death Star, in an attempt to stop the rebels stealing the Death Star plans.
What happened after this (specifically to the remains of the Complex)?
The Imperial Security Complex was likely rendered totally uninhabitable or usable. After consulting the story arc "The Ashes of Jedha" from the canon comic book Star Wars, one can see that the moon Jedha was left essentially unfit to live in, as demonstrated by this panel:
Mind you, this is from a single reactor ignition, the same type that was used on Scarif. Logically one can assume that the Imperial security complex and everything around it were left as nothing but a humongous crater. So far we know nothing about the Empire possibly returning there, but there would be no remnants of the complex to find.
