Since you've already replaced the actuator, checked wires, fuses, and relays—and everything else on the car works fine—this points strongly to either a body control module (BCM) programming issue or a faulty hatch latch assembly.
Here's the thing: on many modern Subarus, a new actuator sometimes needs to be initialized or programmed to the BCM before it'll work. This isn't something a basic scanner can do; it requires Subaru's SSM4 diagnostic software or an advanced bidirectional scanner to complete the initialization sequence. This is a very common missed step and is likely your answer.
If programming checks out, the next suspect is the hatch latch mechanism itself. The actuator may be working fine but the latch is mechanically stuck or misaligned and not responding to it. Try manually cycling the latch to make sure it moves freely.
Take it to a Subaru dealer or a shop with Subaru-specific software. The programming step alone very likely solves this.
