Good question. What is clear but always has been now I look back over the years is that Photrio can always be relied on to give the widest range of answers
What seems to get the widest consensus is that 120 film in sealed foil is fine in a freezer or fridge and can be successfully thawed out
Exposed film for the same reason may attract problems if placed back in either fridge or freezer
What about the situation where there is nowhere in the house that is cool except the fridge/freezer and you cannot develop the film for several weeks or longer?
Do you risk leaving it is the coolest non sunny area in the house such as a cupboard or might it make sense to place exposed 35mm film into a 35mm film container and then into a fridge on the basis that that will stop condensation and with 120 replacing the carefully unwrapped silver foil around it or wrapping kitchen foil around it and sealing it with tape?
However if Nicholas is right and film doesn't have enough heat capacity to cause condensation then none of the
above is necessary. Then the logic of that is that you can store 120 film that has been taken out of its foil or 35mm left in its canister in a fridge or freezer both before and after exposure without worry or so it would seem
