Yes, because the uniform wall structure prevents any dew points within the wall. Additionally, wood absorbs moisture and releases it again with a delay.

So to speak, with a solid wood wall you don’t have problems with mold growth.
With a wooden construction with a vapor barrier, it is possible...
Morning, that's not entirely true. If you have a window connection that is not properly constructed, you could also get mold there. And I haven't seen mold in a timber frame wall like that either, if it is made by a professional company and processed correctly. I also don't quite understand why you are so afraid.
