Recover files from unallocated disk?

I have a16tb pool of data on a QNAP storage LUN. I access it through ISCSI on a Windows 2016 server, and it's labeled as the Q: drive.

I have expanded the LUN in the past, but this time I made the mistake of expanding it to 19TB while still connected to the Windows server.

Now the Q: drive is no longer accessible, and the 19TB of space shows up as Unallocated. Please tell me there's some way to recover the data! I'm afraid to try anything for fear of messing up anything further.

I have already created cases with Dell and QNAP (I'm waiting for QNAP to respond, and Dell did not know of a way to recover the data.)
