You have Hombrew installed in a non-standard location. Mine is in /usr/local/Cellar with the executables linked into /usr/local/bin.

But, assuming other Homebrew commands work when run from Terminal then you might still be okay.

> 3) I created the path $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint and copied libzint. into but replaced dylib with 'so' as suggested on the wiki instructions. So I basically added  lib/luametatex/zint to texmf-osx-64/bin .

"Yes" to creating the path but "no" to copying. Create a symbolic link instead.

So, in Terminal:

  $ cd $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint

  # In my case I used the following:
  $ ln -s /usr/local/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so

  # For you with Homebrew in a different location, try:
  $ ln -s /opt/homebrew/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so

Then steps 4 and 5 as below. I ran the MWE below: the ISBN worked, the ISBNX didn't, the QR code did. This is on Monterey.
