Unfortunately, there is nothing anyone can do to help you with a problem like that.

 

That is a unique key that neither HP or anyone else would have.

 

If you can't obtain it by following the guidance at the link below, if you want to use the notebook again, you will have to reinstall Windows on the drive.

 

Find your BitLocker recovery key - Microsoft Support

 

To reinstall Windows you can use the HP cloud recovery tool on another Windows PC and make a bootable USB recovery drive to factory reset the drive to its 'out of the box' condition.


Here is an info link for how to use the utility:

 

HP Consumer PCs - Using the HP Cloud Recovery Tool in Windows 11 and 10 | HP® Support

 

Since you have to use the utility on another PC, you will have to enter your notebook's full product number in the tool's search window in order to proceed.

 

Your PC's product number is 9P521UA#ABA
