This buck convertor uses the “Bootstrap for Switching MOSFET” circuit I made. I managed to mostly fix the “Cannot find solution” problem by removing the hysteresis necessary for 100% stability and fiddling with some values. At first the MOSFET will be deep in the ohmic region causing it to dissipate lots of heat, but this only lasts a very short amount of time before it calibrates properly after which it will not dissipate too much power.
