What to do in this situation please guide me literally worried about my future

I have joined TCS recently in Mumbai as digital and then after training in java I got forcefully allocated into a project called SBI Belapur and when i enquired about that project I got to know that it never gives release ,it's a black hole project and then they gave me a technology called COBOL which I have no idea and never used and I'm into web3 and ML and on the 1st day only I asked the project manager to please give me some other developer role or front end role atleast but he was very rude and said no and the HR and project manager both were having good understanding of each other and they never give release to anyone and when I asked others asking there what to do they said only way to escape this project is resigning this company . Tell me what to do in this situation where i am having a very worst exp in my first job
