LT3790 Demo circuit convergence issue

Category: Software
Product Number: LT3790
Software Version:

I'm trying to run the LT3790 demo circuit in LTSpice.

It runs fine if I leave everything as "standard" , but if I change V1 (the supply voltage) to a PWL or any other voltage source

Any help appreciated.
