For these kind of errors, I think I've an idea what's the cause in 
<https://issues.guix.gnu.org/58035>.

How did you reboot?  Maybe whatever rebooting mechanism you use doesn't 
do 'sync' first or doesn't wait for 'sync' to complete.

To test the hypothesis that there is store corruption, could you do 
"guix gc --verify=contents" (assuming there are some old system 
generations you can boot from)?
