It seems odd, slicing out huge parts of your code, but, dammit, it works!
It seems that SV is harbouring a grudge against all that C++ and .NET, code, it gets in the way of loading!
I uninstalled as per the usual route, and re-installed, as I’m sure a lot of us have, and it thats not working, right, well, THIS METHOD DOES WORK!
Good luck, its a messy and bloody but an effective solution.
SONY recommend it, and I will too.
I’m so happy I could fly!
