How to get release from a project?

I am a fresher an recently joined a project. They game me development role in RPA(power automate). The workload is lot. I work on weekends and even after office hours yet I am not able to do what is told. Manager is giving false report to client and I think the project might fail. Even after all this when I reached to my delivery partner, he said to work harder. There is no senior developer in the project. All are freshers and given developer role. I dont think I can survive this work environment. All I think about is the deadline for my process. I dont think the pressure and burden they are putting on me for 22k is worth it. I want to leave this project asap but my dp and manager is not allowing. What should I do?
