Module development and code questions

My Drupal 9 platform has a conflict between the Iubenda Integration module and Doubleclick for Publishers (which uses Google Tags).

Iubenda Integration for some reason changes the type attribute of some <script> elements to type="text/plain." This means the JavaScript inside does not run. In this case, it is where the googletag variable is being declared, resulting in multiple errors that say "Uncaught ReferenceError: googeltag is not defined."

Hi everyone, 

I am busy developing a drupal module that pulls data from my companies product and displays it, I have the module working in D7 but during the upgrade process for D9 & 10 I want to make the resulting data easier to theme or plug into existing drupal websites, classically I have just been making routes and serving the template with the occasional theme override

What I would like to know is could I replace that style of working with blocks to make it less dependant on having the theme set up perfectly?

I have a product type with its multiple product variations using 2 or 3 product attributes like color, size, etc. Here is what I am trying to achieve:

On a product detail page whenever the user changes a product variation by selecting a product attribute value i want to show a message for the selected product variation (like Max. purchasable quantity of this variation ). I am using ProductVariationAjaxChangeEvent to fire a ajax command that will alter the markup of that page and add a message somewhere on the page. here is my event subscriber code

I'm getting this error while trying to run Cron. unfortunatly I have no idea where to look anymore. I've seen simular issues but not for commerce recurring. Does anyone have an idea of what could cause this issue? And how can I fix it?

PHP 8.0.27
D9.5.0
Commerce Recurring 8.x-1.0-rc1

I have a project that is heavily depended on Rules. But since Rules is basically useless in D9 & D10 I'm forced to use D7.

A price input greater than 21474836 will cause this error:
