Are you also read as female? Because then your boss might just feel that you steal her show. Academia is highly competitive for women and maybe you can try to mitigate that by finding out what you can do to get on her sunny side.
In my experience if people hate (very strong word!) projects at work, it’s usually rather the case that they’re unhappy with their own work and project this jealousy onto others.
Usually happens within the same gender, or between people who identify as binary against enbies.
I’m sorry, I am fully male-presenting (and was assigned male at birth - which is relevant as my boss is super conservative and would not tolerate a trans person in her office. The LGBTQ lay low here).
My supervisor, however, IS read as female, and I fully suspect that she is who my boss has a problem with. Especially after she left, as my boss saw this as a personal betrayal of sorts. And since my own project is inexorably linked to my supervisor, I get these reactions by association.
