Windows 10: How can I retrieve Bitlocker key?

I’ve purchased a new laptop and logged in using my Microsoft account. Then I removed the Microsoft account. However the disk turned to be encrypted. The key was in the Microsoft account. Currently I cannot boot Windows because it requires BitLocker key. How can I get this Bitlocker key back?

Bitlocker recovery key - can I retrieve it if I'm not locked out?

I have a home PC, not on a domain. My bitlocker key was saved to a USB device that doesn't work anymore. The PC isn't locked out, and I have full access, so can I retrieve the bitlocker key?

The computer has nothing sensitive on it, so if I can't get the key, can I turn bitlocker off?

Many thanks for any help.

 

BitLocker recovery key

My computer is locked by BitLocker and the recovery key is not showing in the Microsoft account (the device is listed). How can I generate/retrieve the key (I don't have it stored anywhere)?
