Joined new company

Hi everyone joined a new company it has been 3 months. I was working for 4-5 hr in my previous.here I have to work 11-12 hours and inspite of that manager says it's less. Colleagues are also not good.everypne just plays politics and due to them my deliverables get delayed. I have 2+ data engineer exp. Please suggest me to come out of this situation. Monday feels like burden the work I felt like doing earlier I had interest in is becoming scarier due to toxic env. Please help
