LM5022 convergence issue

Hello community,

I designed a DC/DC Boost converter with the following characteristics:

- Vin 30-40 V

- Vou 325 V

- Iout 0.6 A

- switching frequency 200 kHz

I am stuck with a convergence issue. I have already tried to change the simulations options: increasing the max time step, GEAR metod and deleting the snubber as well.I hope someone will help me to sollve it.

Thank you in advance.
