How to recover bitlocker data without a key?

Question

Encryption

Good afternoon! and I had two disks in my laptop. System ssd(1) and additional hdd(2). On Windows 10, bitlocker was enabled. I did not know about this. I did not know about any keys and passwords.

Bought a new bigger hdd(3). I replaced an additional one (2) with it. Enjoyed.
Then I bought a larger sdd(4) instead of the system one. I made a bootable flash drive. Rearranged the system.

When it booted up again, I found the hdd (3) encrypted by bitlocker.
I inserted the old hdd (2) into the mobile phone and plugged it into another computer - it was also encrypted.
Went into the microsoft account. Not a word about encrypted bitlocker disks.

Inserted the old sdd (1) with the old system into the laptop, went into encryption and clicked off. Comp unlocked hdd(3).
But I didn't think of inserting it into the system as an external hdd(2). And now I don't know how to decipher it. (I later connected it instead of hdd(3) and tried to turn encryption on and then off - to no avail).
Searched for keys throughout the system - no.

Brothers! It's all? Formatting only? Or is there a way to restore the info?
