That temporary fix saves my skin! Thank you!

It now lets my memoir-using book source compile — PROVIDED that I switch from from backend=bibtex to backend=biber as the option to biblatex.

The weird error if I use biblatex with backend=bibtex (which used to be faster by several seconds than when using biber) is as follows (from the .blg file):

This is BibTeX, Version 0.99d (TeX Live 2020)
Capacity: max_strings=200000, hash_size=200000, hash_prime=170003
The top-level auxiliary file: topology.aux
The style file: biblatex.bst
"front/preface.aux" has a wrong extension---line 47 of file topology.aux
 : \@input{"front/preface.aux"
 :                            }
I'm skipping whatever remains of this command
"back/backmatter.aux" has a wrong extension---line 10220 of file topology.aux
 : \@input{"back/backmatter.aux"
 :                              }
I'm skipping whatever remains of this command
