Should I quit my toxic job?

Hi to whoever is reading this… I currently work in finance and have been dealing with extreme toxicity in my workplace ever since I started 2 years ago. My boss hates me, and he consistently talks shit about my back to my colleagues, always disapproves of my work output, and is overall a horrible person to be around. This job is making me incredibly anxious and depressed. At my old firm, I used to be a top analyst but here I feel miserable and have no career prospects. Everyone is aware of his toxic behaviour, and we had a meeting with his boss to tell him our concerns. His boss told my boss that Ive said negative stuff about him, and now he hates me even more.

Idk what to do now and I genuinely want to quit. For context, im 27, have 400k in savings and dont pay rent so money is not an issue at this point. I did graduate from a top school and have solid work experience, but idk if quitting is the right thing to do.
