Search Builder crashes if you have admin access and CiviGrant is not enabled
This is "search builder" as in the menu option Search -> Search Builder (civicrm/contact/search/builder)
CiviGrant was recently moved to an extension. If you don't have it enabled and have admin access search builder thinks you have access to civigrant and tries to add the component but can't find it:
Error: Class 'CRM_Grant_BAO_Grant' not found in CRM_Core_BAO_Mapping::addComponentFields() (line 764 of ...\CRM\Core\BAO\Mapping.php).
if (CRM_Core_Permission::check('access CiviGrant')) {
$fields['Grant'] = CRM_Grant_BAO_Grant::exportableFields();
