Hello Omar,
My name is Nada, I'm sorry that you are experiencing this issue, and I will try my best to assist you.
I will try my best to assist you with this.
Let me ask you a few questions to provide a proper resolution.
-May I ask who set up the BitLocker on your PC?
-Are you using a work or personal computer?
The BitLocker recovery key is a unique 48-digit numerical password that can be used to unlock your system. This key may be stored in your Microsoft account, printed or saved as a file, or with an organization that is managing the device. The requirement for a recovery key in these cases is a critical component of the protection that BitLocker provides your data.
Here is the link where you can check your BitLocker key using your Microsoft account:
https://account.microsoft.com/devices/recoverykey
onedrive.live.com/recoverykey
