DH unable to migrate old data and use new one

After the newest DH update, when I join the server I've been using it with, it tries to migrate the old data yet fails all the times. Oddly enough after reinstalling the entire mod and removing the old server data, it kept being unable to reuse the newly created one, not loading the new chunks after rejoining the server. The chat logs indicate it's migrating old data for a few seconds, then spams "Distant Horizons data migration for [overworld] stopped." I'm using the Iris + Sodium 1.20.4 DH BETA Installer version while also having the Bliss Shader installed, but not using it.
