IGBT failure and circuit explosion
Without some form of current limiting external to the IGBT, turning it on when there are hundreds of volts on the supply is going to generate a pulse of current due to the physical nature of a discharged capacitor. That current can only be limited by the supply itself and the ESR of the capacitor. The IGBT data sheet says this: -

So, if the pulse of current exceeds 20 amps, you could be in trouble. The IGBT you have used is extremely fast at turning on with a current rise time of typically 3.5 ns and that, to me, suggests it is a candidate to consider.
