LT8312 LTspice sim giving "singular matrix error"

I got the dreaded "time step" error, not the "singular matrix" one. I added a few pF of parallel capacitance to L1 and L2 and the sim ran ok. Loks like you've got about 100V ripple at 100Hz on the output.

From Simulate -> Edit Simulation Command... if you remove Time to Start Saving Data (just delete the 0) and untick Skip Initial Operating Point... it works perfectly
