I ran into an error which I do not know how to rectify with my limited Nix experience. I did google the issue but the solutions are all a couple of years old.
I updated my laptop to 21.11 but during the process, my laptop when into hibernation mode because I was not plugged in (old computer + old battery). The laptop went into hibernation mode before I was able to grab my power cord and plug it in. When the laptop restarted, the update continue without any obvious issues. But now I cannot update my applications:
[root@nixos:/home/sandor]# nix-env --upgrade error: syntax error, unexpected end of file, at /nix/store/7lcwp9xjs0hng1l03ivszzy50dkxqabi-env-manifest.nix:1:1
My searches did lead me to a possible solution, but:

Rolling back is not possible - I have a habit of cleaning (nix-collect-garbage -d) out prior versions when I see everything working correctly. Unfortunately, I think learned my lesson in doing this so soon after updating.
I know I could rebuild this laptop within a couple of hours but is there a better route?
Thank you in advance for teaching me more about Nix.
