New update with error

I’ve updated the Gamipress plugin and now my badges are broken and everywhere is showing me this message:

“[You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘) ) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_520_ci’ at line 1]
CREATE TABLE wp_gamipress_user_earnings_meta ( meta_id bigint(20) UNSIGNED NOT NULL AUTO_INCREMENT , user_earning_id bigint(20) UNSIGNED NOT NULL DEFAULT 0 , meta_key varchar(255) NULL DEFAULT NULL , meta_value longtext NULL DEFAULT NULL , PRIMARY KEY () ) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_520_ci;”

Please I need a solution. Thanks.
