Not in every design. A dual-system or valve-controlled refrigerator can have a section-specific compressor or refrigerant-distribution fault.
If the freezer still freezes food while the refrigerator section warms up, cooling is being produced somewhere. The next question is whether cold air cannot reach the warm section, that section is not being told to cool, or refrigerant is not being distributed correctly.

No. Ice, a blocked return, a fan problem and even testing with another door open can produce the same impression.
It may temporarily restore airflow if ice is blocking it, but it does not repair the reason the ice formed.
