Drupal 8.x

I have a view that is being rendered like this

$view = Views::getView('view_id');
$view->setDisplay('block_1');
$view->execute();
$render = $view->render(); 
$html = \Drupal::service('renderer')->render($render);

The $html variable is being returned in the build method of a Block

public function build() {
    return array(
      '#theme' => 'theme_template',
      '#view' => $html,
    );
  }

Then being outputted in the twig file {{ view }}

Hello. I would like to limit the visible options within a webform select element depending on previous answers. For example: If a user is presented with checkboxes displaying all 7 continents and that user selects Europe, the select element dropdown which is populated with all the countries of the world will only present European countries to the user. Is this possible?

I have a table view with 5 columns and 3 of the columns is a link field. I realized some of the entries have a long names which causes everything to be compacted and misaligned. Currently, it does automatically insert a line break when there's not enough space, but would it be possible to create a line break for a link field where if it exceeds x amount of characters, it'll go to a 2nd line? I'm new to this, so sorry if I missed anything like If I had to create a twig file.

Hello

I'm coming from Drupal 8.7, through 8.9 and I'm now in 9.3

Since D 8.7 I'm repeatedly getting this error whose I like to get rid of. I see it on every page request and it pollutes very much my watchdog. It doesn't seem harming anything though.

I've not the beginning of a clue and  couldn't find anything  that can help on Google.
If someone knows how to solve it or how at least remove this error from filling up my watchdog...
