Module development and code questions

Hello, Sorry I don't if this is an Drupal or React related issue, but I need help on removing this pop-up whenever an anonymous user enters my site.

Hi,

Since I'm not using Composer and don't plan and want to, I have to manually update modules, since (PITA) that option has been removed from latest versions of Drupal (using latest Drupal 11). Mostly there's a version I can download, unpack and then upload over the existing module. With Metatag that seems to be impossible or unadvised, reading this:

Good morning,

Drupal: 10.5.2
PHP: 8.2

I'm getting in my helper with dependency injection:
__construct(): Argument #6 ($time) must be of type Drupal\Core\Datetime\TimeInterface, Drupal\Component\Datetime\Time given, called in /var/www/core/lib/Drupal/Component/DependencyInjection/Container.php on line 261

I'm registering the services.yml in correct order:

I have a content type with checkbox widget. I defined the wedget definition through module.

$form['field_example_123']['widget']['value']['#title'] = t('some text <a href="@url" target="_blank">link text</a>.', ['@url' => '/test']);

The html is rendered as:

I'm trying to develop a module to attach react to various sections of my page, and I've just come across an issue that is baffling me. (a cache issue perhaps? I'm not even sure!)

I build my react app into a file called app.bundle.js, and attach it with a library to a block or paragraph. There's a lot more to it, a couple nuances no doubt, but ultimately it works and is really cool.

This is for a side project and I proceeded with several days of happy developing. I foolishly never tested while logged out. No surprise, everything's broken when logged out (of course). 

I have created few custom blocks in Drupal 11.2, and could successfully insert them via Layout Builder. But when I want to edit them later on, I don't see the 3 icons to manage the content (move/edit /delete). What could be the causes or is there some change I need to make into the src/Plugin/Block code?
