preferences.h lib error in core

[yellowelise]

I have a tech question:
I use #include <Preferences.h> and it's works perfectly in my FIRE but if use in Black m5stack, don't works and core reboot, any possibility to use #include <Preferences.h> in core?

@yellowelise Strange... M5ez works fine on the Fire and on the grey one, it includes Preferences.h. Must say I haven't tested on a black M5Stack.

@rop my problem is with black...
