Encrypted ubuntu missing 20.04 full drive encryption

Summary

I can't boot back into ubuntu after shutting down my machine (by holding the power button after completing updates).

I originally installed ubuntu a few months ago with full disk encryption during the installation steps

I have a running version of Ubuntu Live USB.

I can see my 240 GB SSD drive with the ubuntu existing a /dev/sda by doing sudo lsblk.

I can't access the data inside it (which may be because I installed it with Full Disk Encryption).

When I run sudo cryptsetup luksOpen /dev/sda myvol, I get Device /dev/sda is not a valid LUKS device

When I run pvscan I get No matching physical volumes found

When I run vgscan nothing happens.

When I open GParted, I get a pop up saying Error fsyncing/closing /dev/sda: Input/output error

How can I check if the data is still there/ recoverable / can I boot into my drive?

I don't have a backup of my data, but I know the password to the encryption. I would like to download my data before I format the drive.

Why I had to shut down my machine: I was running ubuntu. I completed an update, and it asked me to restart, but I was holding off. Google chrome then became unresponsive. It said kill Google Chrome / Wait. I clicked click, 10 seconds later, the same dialog box appeared, and continued showing (I.e. nothing was killing Google chrome, I tried at least 20 times). Shutdown also didn't work, so I held the power button for 10 seconds to shut it down. When I restarted, I'm in the GRUB minimal and no longer can boot into ubuntu.

My issue is that my SSD with ubuntu was corrupted. The reason I could get the GNU grub was because I had the GRUB loader installed on another SSD, and it could not reference the broken SSD with ubuntu.

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.
