Hi,

Not long ago, I did this:

  commit 40fd909e3ddee2c46a27a4fe92ed49d3e7ffb413

      gnu: biber: Downgrade to 2.11.

      Biber 2.12 is incompatible with biblatex 3.11, which is what's currently
      packaged.  This is a followup to 41a010875ba4108e666f11fc111cf5bb5dcf5464.

      * gnu/packages/tex.scm (biber): Downgrade to 2.11.

However, it seems that biblatex has been updated in the meantime.

Could you check whether reverting the commit above fixes the problem for
you?

Thanks,
Ludo’.
