Hey guys,
I'm designing a boost converter and I see a very weird spike at the beginning of the simulation that goes until 400V....
Does anyone have an idea why I am seeing this in my simulation?
Thanks a lot guys !

It is far from weird. It is a normal startup transient because the converter is running open loop. You need to develop a soft-start.
Additionally, the default diode is something you never want to use in a boost converter simulation. Pick a garden variety Schottky diode.
