Since old posts are no longer accessible, I will be posting the preface of Davies and Wheatcroft's The Years of Hunger, a scholarly work by mainstream historians, in the comments. The full work is available on Sci-Hub, but it isn't really about debunking the nazi's holodomor narrative. It covers the Soviet famine of the 1930's, the last in a long series of famines in that part of the world. The preface is the only part that is specifically dedicated to debunking, and the explanations for that are in the text of the preface. I found this work in an old post on here while debate-broing on Discord with a bunch of European liberals utterly convinced that Stalin had personally eaten all the grain with his giant spoon. Maybe this can help you when liberals try to label you a genocide denialist.

The author Antony Beevor originated/popularized this. When I tried looking into it I found that he was a NED adjacent historian, and that he was selective with his postwar interviews that he bases the rape of berlin on (think of the narratives that would exist in West Germany with a ramping-up Cold War propaganda campaign). All other claims seem to be sourced back to him, which I also found odd.
That being said lack of credible information doesn't mean that it didn't happen.
