I have 2 hard disks- 128GB SSD, and 1TB. My system drive ( 128gb ssd) encrypted (during Ubuntu 18 installation).
I tried to cancel the encryption, but it's failed, and my second disk (1TB) encrypted to, and my system can't boot. I used the fsck to fix- and now it's can only give me a grub command-line. I have the password of both (the same). I have used live ubuntu, and here the results:

first drive

I have unlocked the 1TB- but I cant mount it and get access to my data.

try to mount

and get an error:

mount /dev/sda4 /mnt
mount: /mnt: unknown filesystem type 'crypto_LUKS'

How can I get my data back?

Second 128GB SSD drive is locked. I have the password- when I boot the system (before braked) I can unlock the 128 drive with the same password.
But now I can't unlock the drive- here is the error:

Can't unlock  128GB SSD

Some pictures of my disks system:

I have installed win8 on 50GB partition, and try to use librecrypt and Ext2Read. Both cannot help me.

I'd appreciate help
