 Hello,


 I ran into the issue when get_option does not return any value:
 get_option( “_wp_session_{$this->session_id}”, array() );

 It returns an empty value, but the value exists in DB and in cache.

 I tested with 3 different methods one-by-one for option
 _wp_session_5c1f3b8058ca4b6cf9e637c31300bc23:

 1) **get_option**
 get_option( “_wp_session_5c1f3b8058ca4b6cf9e637c31300bc23”, array() );
 It returns an empty value (but sometimes it works fine)

 2) **wp_cache_get**
 wp_cache_get( “_wp_session_f5f8546504975ed39fb121b6b1b7c829”, ‘options’ );
 It returns correct value
 `a:6:{s:8:"edd_cart";s:40:"[{"id":79377,"options":[],"quantity":1}]";s:13:"edd_cart_fees";s:0:"";s:18:"edd_resume_payment";s:0:"";s:14:"cart_discounts";s:0:"";s:10:"edd_errors";s:0:"";s:12:"edd_purchase";s:1072:"{"downloads":[{"id":147706,"options":[],"quantity":1}],"fees":[],"subtotal":0,"discount":0,"tax":"0.00","tax_rate":0,"price":0,"purchase_key":"f7f8403a9d9edb93f9be9376d117c1f0","user_email":"","date":"2022-10-31

 ''I removed some private information here.''

 3) **direct DB request**
 $wpdb->get_results(‘SELECT * FROM wp_options WHERE option_name =
 “_wp_session_f5f8546504975ed39fb121b6b1b7c829″‘)
 It returns correct value

 `Array

 So the problem only with function get_option. I checked this function as
 well. It selects values for notoptions
 $notoptions = wp_cache_get( ‘notoptions’, ‘options’ );

 And if current option exists in this array – it do return

 if ( isset( $notoptions[ $option ] ) ) {
                         /**
                          * Filters the default value for an option.
                          *
                          * The dynamic portion of the hook name,
 <code>$option</code>, refers to the option name.
                          *
                          * @since 3.4.0
                          * @since 4.4.0 The <code>$option</code> parameter
 was added.
                          * @since 4.7.0 The <code>$passed_default</code>
 parameter was added to distinguish between a <code>false</code> value and
 the default parameter value.
                          *
                          * @param mixed  $default The default value to
 return if the option does not exist
                          *                        in the database.
                          * @param string $option  Option name.
                          * @param bool   $passed_default Was
 <code>get_option()</code> passed a default value?
                          */
                         return apply_filters( "default_option_{$option}",
 $default, $option, $passed_default );
                 }

 Current option exists in this array, so it applies filter
 “default_option_{$option}”, function filter_default_option. But this
 function check `get_registered_settings`, and there is no information
 about this option, so it returns empty result.

 That’s all information I have so far.

 This problem exists at least for 1 year, for this time we always update
 WordPress core and Plugins for latest version, and it does not any affect.
