guix gc “should” not make a difference, except sometimes software like
Icecat addons do embed store paths in user profiles.  Then guix gc
breaks these.

This “building guix from source” you suggest is a good escape hatch!

Oh yeah, sorry to hear of these troubles.  Old versions of Guix had one
important difference for example: The “builtin:git-download” builtin
builder for git downloads got added into the guix-daemon.  Therefore,
whether a guix-daemon with/without this feature is running changes
the derivation hash, therefore substitutes do not fit anymore.

    gnu: guix: Update to d0438fc.
    
    This adds the “builtin:git-download” derivation builder to guix-daemon,
    added in commit 13b0cf85eb31e1b1ea674debbbfb0f35a32d1374.
    
    * gnu/packages/package-management.scm (guix): Update to d0438fc.
