I’m trying to fix this circuit, and according to my calculations, it should oscillate at around 240 kHz. However, it’s not working as expected.
I’m not sure if I’ve missed something or made a mistake in the design. Could someone please help me figure out what’s wrong?

Try running your simulation without C14 in the circuit. I am not sure about the operation of the rest of the circuit but this capacitor will disrupt the normal phase that is expected on the outputs which is part of the loop stability. Turn it into a pure resistor like 4 ohm or 8 ohm to see if your control loop is operating.
