Read JSON inside array Object from results wordpress

In a DB table from wordpress (Caldera Form plugin), there's a JSON array as value, and from a query, result has this structure :

Array (      [0] => stdClass Object (          [config] => a:22:{              s:2:"ID";              s:15:"CF605df92fa7a17";              s:13:"_last_updated";              s:31:"Sat, 27 Mar 2021 16:44:15 +0000";              s:10:"cf_version";              s:5:"1.9.4";              s:4:"name";              s:29:"Registration for Artists 2021";              s:10:"scroll_top";...}          )       [1] => stdClass Object (          [config] => a:22:{              s:2:"ID";              s:15:"CF605ba79300239";              s:13:"_last_updated";              s:31:"Sat, 27 Mar 2021 16:44:51 +0000";              s:10:"cf_version";              s:5:"1.9.4";              s:4:"name";              s:29:"Inscription des Artistes 2021";              s:10:"scroll_top";...}          )   

How can i read "a:22" then "s:15" inside ? I done a json_decode with [config] value but it return a empty value..
