Runtime Error R6205 Pure Virtual Function Call With 777

Hi all,
Started on FSX:SE recently and downloaded several jets; A380, A330 and B777 from simviation.
These jets are working fine with the exception of B777. Whenever I starts to fly with B777, FSX:SE would quit after some time with a Runtime Error R6205 Pure Virtual Function Call. i tried with the different variants of B777s, the most recent SIA and CX B777 add-on but the same error occurred about 45mins into my flight.
All settings and scenery are on defaults and I tried to lower down the AI flights and vehicles as suggested when I googled for solutions. I tried to uninstall and re-install FSX:SE and Windows 10 several times. However, the error still persisted.
Nowadays, I only fly the A380 and A330 to avoid the error. i would really love to fly the B777 again.
Anyone encounter this error and possible solutions to overcome it?
