`lua/hlchunk/utils/indentHelper.lua:28: attempt to perform arithmetic on local 'leftcol' (a nil value)` error when terminal width is less than 138 cols

[msva]

Describe the bug
When I open nvim with hlchunk installed and configured, and if terminal width is less that 138 cols, I'm getting following error on nvim startup:

...vim/lazy/hlchunk.nvim/lua/hlchunk/utils/indentHelper.lua:28: attempt to perform arithmetic on local 'leftcol' (a nil value)

Screenshots

Maybe it is worth to add something like or 0 (or something like that) there?

Well, it seems that it also sometimes appears not even when width is <138 cols.
Just nvim don't wait for I press enter, and boots further.

I just found that is also appears when I editing nvim lua config with full width (236 cols)

(also, happens only when blank module is enabled)
