These suggestions about cutting management and livers is just Niji absorbing the branch with another name. The fact is that most people don't forgive/forget after fuck ups like this that completely sour the brand regardless of what the company does to fix itself. Neither fixing every single problem or doing absolutely nothing will make any difference on this.
All that will happen either way is that it will stagnate with whatever fans that stayed and eventually, very slowly, start growing again with new fans that aren't familiar with what happened (new to vtubers in general) and old fans that want to watch their oshi again and have cooled their feelings enough to look past what happened. Its going to take years, but EN is going to be "fine." All the collapse that we saw this year really did was speed up what had been happening for over a year anyways.
