[Synapse 4] Custom Key Remaps & Macros Completely Fail to Register on DeathAdder V3 (Stuck on Generic HID Profile)

I am experiencing a critical issue with Razer Synapse 4 where the software completely refuses to write or apply any custom configurations, macros, or keyboard rebinds down to my wired Razer DeathAdder V3.

When I assign a macro (e.g., an automated "E" key loop) or a basic keyboard function directly to Mouse Button 4, Synapse 4 visually displays the change as saved and linked on my monitor. However, the physical hardware continues to act strictly as standard Mouse Button 4, ignoring the profile.

Here is everything I have checked and done to isolate the issue:

1. Verified that the Macro module is fully installed and up to date under the Synapse 4 "Devices & Modules" management dashboard.
2. Checked active Windows background processes: RzActionSvc (Razer Central Service) and companion engine assets are running normally.
3. Cleared local app configurations by deleting both the %localappdata%\Razer and %appdata%\Razer temporary profile cache folders to resolve any corrupted migration states.
4. Executed a clean hardware profile reset via the native "Repair" utility inside the Windows Programs and Features controller.
5. Dropped the device polling rate to 500Hz to eliminate potential data-packet crowding over the USB track.
6. Swapped physical motherboard USB 3.0 ports on the back panel to trigger a clean driver initialization.

Despite Synapse 4 being open and active, Windows continues to flag the primary pointer slots as a generic "HID-compliant mouse" in Device Manager, and the live mapping container inside RzActionSvc is failing to push the button configurations down to the device interface.

What is blocking Synapse 4 from communicating the active layout overrides to the mouse, and how can I force the hardware layer out of this generic profile loop?

Any guidance or patch workarounds from the team would be highly appreciated!
