Charcoal (evaporation) canister failed. Due to treatment of mold in the AC unit? on 2000 Toyota Camry

My mechanic fixed a problem with mold in the A/C, the radio didn't work for a day, and now the charcoal canister needs replacing. Do you think the flushing of the A/C was related to the failure of the canister?
