Maybe use your network of people that were good to work with; can you reach out to your former manager you clicked with or any former teammates you liked and say hey, I'm ready for my next role, I liked working with you, do you have anything open on your team or do you know of any good teams with openings? If they ask why, just say you want to try something new. Which is true. You don't need to unload about your current predicament or criticize your current boss, just be upbeat and clear that you want a new role. People will either pick up that something is wrong and appreciate your tact and respect your privacy, or, when you say you just want something new, they'll simply believe you and not start overthinking, prying, and dissecting, which is hard to remember when your current role is making you feel like you're bad and everyone is horrible.
Best of luck, you are worthy no matter what your current environment is making you feel.
