restore complete partition of a veracrypt hdd

[mark]

I request urgent help.
info hdd:
I created a veracrypt partition on my hdd of about 2 Tb, with the standard Veracrypt volume. Inside the hard disk there was only one veracrypt partition.
Problem:
Unfortunately I reset the whole hard disk with Disk Utility (mac os) with "faster" security level. So in theory it did not overwrite anything at least I think.
Nb: I have an old backup of the same hdd but I urgently need to restore this hdd.

I'm using RECOVERY to see the results of the scan, but the result is very confusing (I put the partial screen of the result).
What I know is that if the partition has not been overwritten several times, it is possible to recover the files in it almost always. But having encrypted all the hard disk I do not know which file to look for.

I could find the way it was initialized:
