TPS61089: Amplifier circuit simulation error using TPS61089 boost converter supply

Tool/software:

Greetings,

I'm currently trying to simulate an amplifier circuit using an LM1875 in PSpice. The amp has a +12/-12 V supply from another circuit using an TPS61089 boost converter to convert 3.3V to 12V.

I have simulated both circuits separately (LM1875 with ideal voltage sources first) and the simulations are satisfying. But when I try using the boost converter circuit to supply the amplifier circuit, I get some convergence error in simulation. I have provided the picture of both schematics and the output window with the error below.

What am I doing wrong ?

Thanks for your help!
