The Castaway Achievement still is not working

I've reported this bug for the past three versions of Minecraft ( 1.19.20, 1.19.10, and 1.19.0), and yet even though the past two times I've reported it, Moment has claimed they patched the Castaway Achievement, I still cannot get the achievement to pop no matter what I do. I've tried in probably 50 different worlds where all I did was spend three days eating nothing but dried kelp, and yet I still am not receiving the achievement. Mojang, please fix this!
