The only way to bypass the Bitlocker key is to completely reinstall Windows. It is possible you may have a different Bitlocker code. It is possible to check the key on your Microsoft account.
Here are the instructions on how to check the Bitlocker in your account.
Please go to Microsoft.com and sign on to your account.
Then click on My Microsoft Account
Click on view details for the computer with the problem.
Then click on the Manager Recovery Keys.
You should see the key for your computer.
It is possible to copy and paste the code.

If you are not able to find the current Bitlocker key, it is possible to clean-install Windows. I have enclosed the instructions below. You will lose all the data on your computer with this option.
I have enclosed a link below where you can download the clean version of Windows 11.
You will need a formatted, empty USB Drive with at least 10 GB of space.
Click on Create a Windows 11 installation media. Then follow the prompts.
