Como consertar grep quebrado no Debian

Atualizei meu sistema para o Debian bookworm e o processo pareceu prosseguir normalmente, mas terminou com alguns erros. Quando tento usar o apt para resolver o problema, acabo com uma tela cheia do seguinte erro:

grep: symbol lookup error: grep: undefined symbol: pcre2_set_compile_extra_options_8

Parece que qualquer tentativa de usar grep resulta nesse erro, não importa quão básico seja o comando. Então, suponho que grep esteja de alguma forma quebrado neste sistema agora, o que dificulta qualquer esforço para repará-lo usando apt ou dpkg, por exemplo:

$ sudo apt install -f

O problema parece esotérico e meus esforços para encontrar uma solução foram improdutivos. Alguém pode me ajudar?
