Windows 10: Cannot access bitlocker recovery key as my device has been removed from device list

I cannot access my bitlocker recovery key. I was able to access it once and did not write it down by going to aka.ms/aadrecoverykey, which took me to the 'devices' window of my Microsoft account. From there, I clicked on my laptop and accessed the bitlocker key, and was able to enter my device.However, it logged me out again and is requesting my recovery key. When I followed the link to my 'devices' window on my Microsoft account, I found that my laptop had been removed from my devices. As a result, I can no longer access my bitlocker recovery key.Please advise how to get my key back, whethe

How to define [Device] - [BitLocker recovery key] pair

I want to delete not-associated-with-any-pc BitLocker recovery key. Device name in 'About' and that shown on the listing page for BitLocker recovery key seems to be different. Windows installed date in 'About' and registered date for BitLocker seems to
be different, too. As my desktop devices experienced reinstall at problem before, it is uncertain which device listed are actually in use. If a bootable USB could be counted, I wish know how to identify them, too. Thank you very much.
