Thank you for reporting this @ShafiqAiman94. Looking at the logs, I see:

EXT4-fs (sdc): Remounting filesystem read-only, which is probably the root cause of the issue you're seeing.

Can you follow these instructions to repair your filesystem ? This should resolve the issue.

Thanks @OneBlue, that worked for me. I couldn't see the logs but searching this error code led me here.
I used a second distribution (Ubuntu) to recover like so:

PS> wsl -d Ubuntu --mount C:\Users\User\AppData\Local\Jammy\ext4.vhdx --vhd --bare
The operation completed successfully.
PS> wsl -d Ubuntu lsblk
