Why do you not have the private key? In general, there is no known way to figure out the private key, given a specific bitcoin address. Bitcoins security depends on this. I invested my bitcoins in someone's miner. He requested for me a new miner and told me to fund. Right now I want to withdraw my bitcoins I invested but he is asking me to pay him so that he can give me my private key..
This is a scam. Mining does not work that way, if you deposit more money you will not see it returned. Changing your password means nothing if the attacker had access to your account in the past, he will have copied down your recovery phrase, and will be able to recreate your wallet on another device, without needing any passwords. Unfortunately that is the case, sorry for your losses. At this point, transfer any remaining BTC out of that wallet, and never use that wallet ever again.
I've seen this scam before, I expect the scammer copied your seed phrase down and made a second copy of your wallet, so any BTC you send to that wallet now will be immediately stolen by the scammer.
