I have reassigned this to t-coffee only. The package libbio-tools-run-alignment-tcoffee-perl is just a perl wrapper to the t-coffee program, and it's t-coffee that is failing on its own.
t-coffee's own autopkgtest fails since 12.00.fb08c2-1. See
https://ci.debian.net/packages/t/t-coffee/unstable/amd64/
