The central problem with the Nova Vulgata is that this translation is the consensus work of modern academics.
Arguing that they had access to manuscripts unavailable to either Jerome or the Counterreformation editors of the Clementine Vulgate, contemporary academics (note that I use this term again rather than "scholars") claim that the NV is a cleaner, more accurate critical edition for the Latin bible. Behind this an unspoken, modernist assumption that the older Vulgate edition is lacking and inaccurate whilst the manuscripts to which modern academics have access possess content that can correct those claimed defects.
The Church of the 20th and 21st centuries has suffered under a Dictatorship of the Academy.
