Usually changing temps will not cause a fridge to stop cooling. But, most fridges have a showroom mode and I suspect it was accidental entered. Look on user interface for on/off and then press and hold. Good luck!
turn freezer to mid point and try fridge on 3.5 as a starting point.
Keep the refrigerator temperature at or below 40° F (4° C). Thefreezer temperature should be 0° F (-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these temperatures and are generally inexpensive.

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp. The problem could be the electronic control if you have one or the mechanical linkages.
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You obviously still have a defrost problem so here is info to help solve it.
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.
If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.
If the defrost thermostat is bad, it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad. With an ohm meter it should show continuity when cold and none when warm. You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.
The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.
If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good.

You can turn the defrost timer till it clicks
and everything shuts down. The heater should now come on. If it does, replace
the timer. If it doesn't, check the heater and defrost thermostat. Turn the
timer again till everything starts back up to end the defrost cycle.

the defrost timer/ board is getting stuck in defrost and when you unplug it and plug it back in it resets the defrost timer/control board.
you may need to replace the defrost timer/control board.
