Before you change anything, can you post your .guix-profile/manifest file? 
Maybe it will help us understand what's going on on your side. You're actually 
the second user we hear that from, but we thought they might have tried to 
install things in parallel. It could explain some of your symptoms too, but not 
the manifest issue.

Whenever guix started acting crazy for me, it was because of a disk failure or 
corruption. You should probably try to run fsck on your root partition.
