Hello again, We have a quick hotfix that will allow Mods that haven't been updated for the Utopian Abundance changes pass any of the DLC checks they may have for Utopia, Synthetic Dawn, or the Humanoids Species Pack.
Stellaris 4.3.7 is now available for download via Steam and GOG, with MS Store following as soon as it passes certification.
The DLC ownership check has been made backward compatible for any mod that happens to still include them.
Carry on!
