Did you ever try the zsh solution that another user gave you to your
original question (https://unix.stackexchange.com/q/673509/116858)?  It
seems to me that using a single utility that has the filename globbing
capabilities that you require seems more reasonable than using a
pipeline of text manipulation tools.

In any case, this has since a while no longer been a bash-related issue.
Your awk issue here is due to your specific awk (probably busybox awk)
not implementing the same extensions to standard awk as GNU awk or mawk
does.
