Assume a flat universe, Dark Matter, Dark Energy and inflation were assumed to exist in the early universe in order to predict the current anisotropies and the acoustic sound peaks observed in the CMB. Dark Matter and Dark Energy have never been detected while inflation is not even a scientific theory. Dwarf galaxies don't fit standard model and challenges cold dark matter cosmology. Large scale structure formation assumes the presence of dark matter in the early universe. However, most early massive galaxies are strongly dominated by normal matter. The CMB predictions for H0 assume that the contents of the universe are well described by atomic matter, cold dark matter, and dark energy. If this description is incomplete, the predictions could be wrong.
