The upstream project is in MS Github which is a non-starter for
me. I’ll go as far as /reading/ from the site. I’m surprised such a
crippling bug has not been reported there, but I found this comment:

Apparently Bookworm is using the absolute latest version of acro
(3.8). So from the Debian side, the acro version needs to be rolled
back. I have made use of the X-Debbugs-Cc feature on this message to
get the author in the loop, which I guess I should have done on the
submission.
