Hm, although Dea Dia has been near the top of my modlist of things to prune from the Lite version of this modpack, the current version shouldn't have any compatibility problems (and despite the ALPHA in the title, it has been a perfectly functional planet mod)
Your error sounds a lot like this issue, which may involve resetting the mod settings from your end, because I am able to load up with Frost Biters v2.2.0 and Dea Dia v0.30.18, both standalone and as part of the other modpacks. Running default settings for all required mods in the modpack.
Only reason I might consider removing it, is just because of the upcoming update that would completely rebalance how the mod plays (or so I've heard? I haven't looked into it in a long while) Current version should load up just fine though
