What were you trying to do (and why)?

I want to use bash completion

What happened (include all command output)?

when my bash_profile try to run script for bash completion that include /opt/homebrew/etc/bash_completion.d/brew then I see error:

-bash: /opt/homebrew/etc/bash_completion.d/brew: line 27: syntax error near unexpected token `<'
-bash: /opt/homebrew/etc/bash_completion.d/brew: line 27: `  while read -r line; do COMPREPLY+=("${line}"); done < <(compgen -W "${list}" -- "${cur}")'

What did you expect to happen?

not see error

Step-by-step reproduction instructions (by running brew commands)

Remove bash completion, remove /opt/homebrew/etc/bash_completion.d/brew file
now everything works
install bash-comletion:

brew install bash-completion

error again show
