Royer Induction heater

This is the exact circuit found on markobakula.WordPress.com/power-electronics/500w-royer-induction-heater/
I found this searching for induction heaters, all credits go to Vladomiro Mazzilli, with modification credits going to Marko for turning it from an induction charger to an induction heater.

Everycircuit really does not like this circuit and I was wondering if there is a way to make it work in here. He has a video of it working so I can only assume it really does work and this found a limitation in every circuit...
 
Edit: added resistance to the two coils to induce a swing... We are dealing with a pure electrical environment after all!! (A simulation)

More edit: small inconsistencies have been added in, in an effort to make this astable  configuration come out of equilibrium. No success..

Help is as always greatly appreciated!

Erroneous components are highlighted in red. There is no resistance with the inductors, therefore the program cannot calculate any parameters

I added a 110k resistor to the coil in series, but I don't think it operating the way its meant to, it doesn't resonate. But maybe you can figure it out with adding a resistor were needed and with the proper ohms.

Put 10mOhm in series with inductors. Than you can simulate, but it still doesn't oscillate...

The oscillation is in the main coil and cap. Use n channel fets and slow down the simulation speed.

Oh dumb me using p channel lol

Just updated the coil to be approximately 5 turns in a space 5cm wide by 8 cm tall

Thank you rich for that great answer, it makes sense that too many variables are missing with no actual load in the way of the power source
