Good day! I'm Raniel. I understand your frustration regarding this issue and I'll do my best to help.
Kindly double-check if you'll be able to find your recovery key on your Microsoft account using this link instead: https://account.microsoft.com/devices/recoveryk...
or via OneDrive: https://onedrive.live.com/RecoveryKey
I also suggest that you refer to this article for further details on how to find your Bitlocker key: https://support.microsoft.com/en-us/windows/fin...
If that didn't work, you may also go through the methods provided by Greg Carmack - Windows MVP 2010-2020 (retired) on this thread with a similar issue that you're experiencing: https://answers.microsoft.com/en-us/windows/for...
However, if the issue still persist, see if you'll be able to rescue your files, then perform a clean install of Windows instead. Kindly refer to these articles as guides:
