I do not have a answer. My computer did not like the transistors models. "could not find" I changed to different parts. Still not happy. I removed the transistors and diodes etc. and just have the op-amps. (close the feed back loop) Now it works.

Now I see R6 and R16. Look at them close!

You LTspice circuit shows a floating voltage source, which the AD2S1210 does not provide.
You need two grounded voltage sources, with their relative phase being 180°.
