Lost of Bitlocker Recovery Key


I got my “My Passport Ultra” bitlocker locked…
Previously, i had formatted my pc from window 8 to 10. After i formatted, I’m trying to access to my drive It asked from me the recovery key. I think it had locked the whole drive.
Is there any method to get my data back without format it? I contain my whole degree portfolio and i need it madly…

Bitlocker is handled by and through Windows.
