It looks like these are the actual errors:
/tmp/guix-build-deja-dup-34.3.drv-0/deja-dup-34.3/libdeja/ToolPlugin.vala:78.7-78.40: error: Assignment: Cannot convert from `GLib.List<weak GLib.File>' to `GLib.List<GLib.File>'
      this._restore_files = value.copy();
/tmp/guix-build-deja-dup-34.3.drv-0/deja-dup-34.3/libdeja/CommonUtils.vala:397.65-397.78: error: The name `g_object_unref' does not exist in the context of `DejaDup.set_settings_read_only'
                                                                g_object_unref);
                                                                ^^^^^^^^^^^^^^

      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


It probably keeps going after the errors due to make's parallelism.
