Can not use # hash mark in todo-tree.regex.subTagRegex

[cnf]

I hope this is not filed before, it seems hard to search for # 🥲

it does not seem possible to use # in todo-tree.regex.subTagRegex. I am trying to use ^\s*#(\d+) and that and any variety of that gives me Cannot read properties of undefined (reading 'filter')

It works with other symbols, such as @ or & etc, but not with # escaping it with \# also does not work.

edit: i am on version 0.0.226 in vscode
