Windows 10: how to recover BitLocker key which connects with account that I cannot loggin

I recently reset my laptop and logged in with my new Microsoft account since I forgot my old account's password. But my drive was locked by BitLocker which connected to my old account. Meanwhile, I am not able to recover its password since I was told the email which connected to that old account was closed by administrator, and I need to pay money in order to unlock it. What should I do to get my BitLocker key to unlock my drive?

Recover BitLocker key from Key ID

It doesn't work. The specific device I need to recover the key is not on the list, neither an option to retrieve the BitLocker code using its Key ID as the blue screen says.
