Two errors | WordPress.org

Hello dear team. I am asking for your help.

When I open the Widgets page (/wp-admin/widgets.php) I see the following error at the top:

Warning: Undefined array key 1 in /home/doxologi/public_html/wp-includes/rest-api/endpoints/class-wp-rest-widgets-controller.php on line 711

Also, very often when I open any link on my site, I see the following error displayed on a white background:

Fatal error: Uncaught Error: Call to undefined function wp_cache_get() in /home/doxologi/public_html/wp-includes/option.php:165 Stack trace: #0 /home/doxologi/public_html/wp-includes/l10n.php(63): get_option() #1 /home/doxologi/public_html/wp-includes/l10n.php(139): get_locale() #2 /home/doxologi/public_html/wp-includes/l10n.php(766): determine_locale() #3 /home/doxologi/public_html/wp-includes/load.php(1395): load_textdomain() #4 /home/doxologi/public_html/wp-includes/class-wpdb.php(1815): wp_load_translations_early() #5 /home/doxologi/public_html/wp-includes/class-wpdb.php(734): wpdb->db_connect() #6 /home/doxologi/public_html/wp-includes/load.php(562): wpdb->__construct() #7 /home/doxologi/public_html/wp-settings.php(124): require_wp_db() #8 /home/doxologi/public_html/wp-config.php(95): require_once('...') #9 /home/doxologi/public_html/wp-load.php(50): require_once('...') #10 /home/doxologi/public_html/wp-blog-header.php(13): require_once('...') #11 /home/doxologi/public_html/index.php(17): require('...') #12 {main} thrown in /home/doxologi/public_html/wp-includes/option.php on line 165

Fatal error: Uncaught Error: Call to a member function set() on null in /home/doxologi/public_html/wp-includes/l10n.php:784 Stack trace: #0 /home/doxologi/public_html/wp-includes/l10n.php(872): load_textdomain() #1 /home/doxologi/public_html/wp-includes/class-wp-fatal-error-handler.php(47): load_default_textdomain() #2 [internal function]: WP_Fatal_Error_Handler->handle() #3 {main} thrown in /home/doxologi/public_html/wp-includes/l10n.php on line 784

Please help me to solve these two problems. Thank you very much.

Best wishes and blessings,
Alexander Angelov.
