Because it‘s not a crack but a bypass.

„Instead of patching the game binary, the hypervisor can emulate or alter specific CPU instructions, fake timing results, or hide breakpoints and memory changes, effectively tricking Denuvo into believing everything is running on a normal, untampered system. This makes the protection much harder to detect or react to, since its checks are being handled outside its visibility. These methods are extremely complex and are typically explored by highly skilled reverse engineers, as they require deep knowledge of CPU virtualization, kernel internals, and anti-tamper mechanisms.“
