+Uh-oh, after adding the option `--test-debug` to the `test` subcommand I got a lead on
+the real culprit and it wasn't git-annex but libmagic:

+
+So the real error turned out to be a user failure of mine: libmagic (or the msys2 package `mingw-w64-x86_64-file`)
+had a recent update and the new library didn't like my previous magic database located in the fallback location
+`%localappdata%\.magic\magic.mgc`. By copying the msys2 file `/mingw64/share/misc/magic.mgc` to the aforementioned
+location, the whole issue cleared itself and this report became moot.
