How to recreate the user_picture field?
Instead of importing configuration as suggested previously, you could as an alternative, programmatically re-create the field. Here is some code that does that.

&lt;?php

use Drupal\field\Entity\FieldConfig;
use Drupal\field\Entity\FieldStorageConfig;


// Create the user profile field and instance.
FieldStorageConfig::create([
  'entity_type' =&gt; 'user',
  'field_name' =&gt; 'user_picture',
  'type' =&gt; 'image',
  'translatable' =&gt; '0',
])-&gt;save();
FieldConfig::create([
  'label' =&gt; 'User Picture',
  'description' =&gt; '',
  'field_name' =&gt; 'user_picture',
  'entity_type' =&gt; 'user',
  'bundle' =&gt; 'user',
  'required' =&gt; 0,
])-&gt;save();


Assuming the code above is placed in a file called recreateUserPicture.php that is stored in your docroot, you can run the following Drush command:

drush scr recreateUserPicture.php


Best of luck!

N.B.: An alternative answer (since the importing of configuration from the standard profile has a problem with having the field being available in Views UI).
