After update Ubuntu cryptsetup password is incorrect

cn flag

I have Ubuntu 20.04. It was encrypted during installation. It is a virtual machine on ESXi host. Today I tried to run ubuntu but my password was not accepted, I saw the error:

"cryptsetup: error: sda6_crypt: cryptsetup failed, bad password or option?".

  • I tried to boot with an old kernel Ubuntu 5.15.0-50 instead of 5.15.0-56, but it does not accept a password either.
  • I booted using a live CD and tried to unlock the disk - successfully, so my password is correct.

Questions:

  • How to fix the password issues?
  • or How to decrypt the disk to prevent input password at all?

Last time I successfully run it 1 month ago, but today something went wrong.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
