composer require 'drupal/tawkto:^1.4'

we noticed the installed code does not match the tag in drupalcode (https://git.drupalcode.org/project/tawkto/-/tree/8.x-1.4?ref_type=tags)

I have run into an issue with a complex Ajax enabled form in a custom module (Drupal 9.5). In certain error scenarios I get 

Symfony\Component\HttpKernel\Exception\HttpException: The specified #ajax callback is empty or not callable

Hi all,
I’m encountering errors related to missing libraries in Drupal:
Commerce Price requires the commerceguys/intl library.
Address requires the commerceguys/addressing library.

In composer.json, I have:
"commerceguys/addressing": "dev-master",
"commerceguys/intl": "^dev-master"
I've run composer update and cleared the cache, but the issue persists. 
Any other steps to fix this?
