Need genuine advice

Hello everyone... I'm working in an early stage startup, things with my product team are really good but with the rest of the team like tech, marketing & sales it's really toxic...and I witness that toxicity regularly not directly but indirectly & from time to time I have to witness the same toxicity during stakeholder meeting plus the office vibe is also not that good kind of drains my energy Now when I tried to put down my papers my manager tried to give me a good raise currently I'm at 8 LPA with 1 year of experience & he is giving me a raise of 50% (12 LPA) Now I'm really confused about what to do...need suggestions
