Memory issue using Drupal CMS

Problem/Motivation

I'm currently playing with Drupal CMS (2.0.2).

After Drupal CMS get installed, I uninstalled Canvas.

I installed Paragraphs after creating a Paragraph with a Paragraphs field I get Memory issue with fatal that prevents me to use Display Builder.

eg:

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /var/www/html/web/core/lib/Drupal/Core/Field/FieldItemBase.php on line 143

OR

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 16384 bytes) in /var/www/html/web/core/lib/Drupal/Core/Entity/TypedData/EntityDataDefinition.php on line 135

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /var/www/html/web/core/lib/Drupal/Core/Database/Query/Select.php on line 651

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /var/www/html/web/core/includes/errors.inc on line 26
