Error after placing Pseudo Title Formatted on D10.1.6

This is because a static method is using $this
In fact it's using $this->t(..something here...)
When it should just be using t() without $this.
You get an error of with the current code because you shouldn't call $this in a static context.
Maybe newer version of PHP are more strict on that?

So the fix is changing

      '#title' => $this->t('Link to the entity'),

to

      '#title' => t('Link to the entity'),

For all usages of $this->t()

Seems there is confusion of what t() to use.

Confirming same problem Drupal 10.2.6 using the formatted field in the display for a content type. Applying patch via composer works and fixes issues.
