LTspice simulation of inverter just stops working

Why all those -5V supplies rather than just one? Why 2 x 10uH inductors in series at the output rather than one 20uH inductor? Unnecessary components and circuit nodes will slow down the simulation.
Reducing the number of RC filter stages at the input gets the sim to run past the 56mS point.
Like Lightium, I found missing pin connections. Perhaps the IC model asy files you use are not the same ones as I use. Analog Devices may have updated them?
 
any tips on speeding this particular sim up appreciated?
Divide it into modules and sim each module separately. That should identify which module is causing LTS to struggle.
