Can't unlock encrypted disk

Can't unlock encrypted disk
I use Debian default encryption disk encryption. Only /boot it's not encrypted. When I boot I need to type my password, and then I will be logged in. But now I can't login. It always says that I typed the wrong password, but I typed the correct password.
I tried to boot in live-CD and try unlock volume from there. But It always says wrong password.
Before that I had an achieve that had a 90GB file in it and I tried to underachieve it, but it gave me error not enough space. I get notification that I'm out of space 600mb left, but when type df -h I saw I have same amount of space as before I start to unarchieving file. Looks like file was autodeleted by Debian system.
I have no BADs on disk. Sometimes I have some issues with RAM module and I my PC stucks but I always can unlock the disk. In that case I need to clean RAM module and PC is not stucking anymore. I tried remove RAM modules and boot with only one of them, but still can't unlock disk. I have 2 HDDs with Debian and only one of them is not unlocking. Other one is working fine. I will try to connect that HDD to another PC and try to unlock and then type here if it succeed

yhsm-keystore-unlock(1) General Commands Manual yhsm-keystore-unlock(1) NAME
yhsm-keystore-unlock - Unlock the keystore in a YubiHSM SYNOPSIS
yhsm-keystore-unlock [options] DESCRIPTION
In versions of the YubiHSM before 1.0, the YubiHSM could be protected using a 'HSM password'. The YubiHSM would unlock it's cryptographic functions if the correct password was given, but it was a simple comparision test. In YubiHSM 1.0, the password was changed into an actual key that was used to decrypt the contents of the YubiHSM internal key store, which was then AES-256 encrypted using the new 'Master key' when stored in the device. In YubiHSM 1.0, the option to also require an YubiKey OTP to unlock the keystore was also added. One or more 'Admin YubiKeys' can be con- figured in the YubiHSM, and an OTP from one of these must also be provided before the YubiHSM will enable it's cryptographic functions. The OTP is simply validated against the non-encrypted internal database (not key store) in the YubiHSM though, but together with a 'Master key' not stored on the server with the YubiHSM, it provides enhanced security by being a second factor that an attacker can't just inter- cept even if the server is compromised. OPTIONS
-D, --device device file name (default: /dev/ttyACM0). -v, --verbose enable verbose operation. --debug enable debug printout, including all data sent to/from YubiHSM. --no-otp skip the prompt for an OTP. For use by scripts where no OTP is required and the Master Key is stored on the server with the YubiHSM. --stdin read password and/or OTP from stdin rather than prompting for them. Python prompts does not accept piped input, so this option have to be used to unlock the YubiHSM from a script for example. EXIT STATUS
0 YubiHSM keystore successfully unlocked. 1 Failed to unlock keystore. BUGS
