Cant autocomplete "unzip"-command

When I try to use the command "unzip " on any folder I immediately get the line

unzip ls: cannot access 'tmp': No such file or directory
ls: cannot access 'tmp': No such file or directory
^C

which is particularly weird to me, cause my alias

alias |grep -i unzip
alias unpack='unzip'

works perfectly fine. the unzip command still works, though cant be autocompleted.

I tried “sudo apt reinstall bash-completion” with no difference.
