The fan does not work and there is frost on the lower back wall. Some items on the top shelf do not freeze but most are o k
SOURCE: the freezer doesn't work properly
If there is no cooling at all , before we go further we must confirm the first step of confirming the compressor and gas pressure. So shut off the fridge and leave it off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge. If there is no ice formation we have a big issue as the compressor and gas must be checked out. If compressor is running check the pressure, get help to test gas pressure. If not you will need to fill up ,If gas pressure is good the possibility of the compressor being inefficient is high. In such a case you must take consensus to estimate and decide, if RPM of motor is low check capacitor.
However if Ice forms then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test from the outside and make your observations so that we come to the solution

This could be the fan or the switch that controls that defrost cycle. The only way to tell is to use a volt meter to see if there is electric current to the fan motor. IF there is current, replace the fan.

Question edited for typo and capitalisation.
Classic symptoms of a fridge that needs a refrigerant gas top up. You will need a service call.
Testimonial: "Many thanks, however what could be the reasons for insufficent refrigerant, knowing that I only used the fridge for 1 year, I bought new in 2009 and and started using in april 2021"
