Recover an accidentally initialized Bitlocker partition

NOTE: Before you downvote or mark as duplicate, please note that i DID look around and while i found similar issues on stackexchange and elsewhere, I wasn't able to go very far.

In short, I have a 1TB HDD which contained only 1 partition that filled the first 500GB. That partition was encrypted with Bitlocker, for which I still have both the password and recovery Key.

Through a series of catastrophic fails on my behalf, I have managed to execute the diskpart clean command on that drive and also later Initialize the HDD with Disk Management.

I've tried many recovery tools but none gave me any of the recent files i'm looking for, most likely because they're encrypted.

Later I came across this which set my hopes up, but then when I followed the steps, i'm still unable to open the created img file and access the data.

So my questions are:

• How likely is it that all or most my data is still there?
• Do I still have any hopes of recovering it? Even partially (as in, not all the files, but not partial/non readable files)
• Is there perhaps a way to recreate the partition while leaving the data intact and tricking windows into thinking it's a "current" bitlocker encrypted drive so i can unlock it with the passphrase?

Thanks!
