I have tried everything that were suggested...adjusted turbulence to low, unbind autopilot keys, no live weather, increase sensitivities of flight stick to 5%, no auto rudder and other stick controls etc.....nothing works. Seems these intermittent autopilot disengage happens on every flight but with varying frequencies...the most frustrating thing about flying the aircraft. I am at wit's end as to how to neutralise this very frequent autopilot dis-engaging. One factor that would make me give up on flying this aircraft. Starting to regret on my purchase of the Inibuilds A380. The free FBW A380 flies flawlessly.

Maybe it's one of the controls (hardware) that's causing the issue? I had the same long time ago for another add-on. Perhaps, try clearing out the control inputs and only add the primary inputs that are necessary and see if that works. I'm though aware of FBW flying flawless with your current setup and presets/assignments.
