The circulation wasn't working so I replaced the humidity sensor and shortly after a couple of minutes the lightning bolt showed up and it’s not going, and I lost all power to the car.

Hello, try unplugging the humidity sensor and see if the vehicle will start. The sensor is on the Lin bus data network, its possible you have a bad new sensor and its pulling the network down. I would also check Fuse 45 15amp, its the ignition fuse to the humidity sensor, was this an aftermarket sensor or did you get it at a dealership?

Here is the wiring diagram for the sensor and its power feed.

These are the other components on Fuse 45, of the interior fuse panel.
