Unable to search WP plug in directory since update

Hi Today I updated our twenty seventeen theme to WP 5.0 and a host of plugins (listed at the bottom) Reading other folks posts in the forum it went quite well.

There is one issue that I would like to resolve;
When I search to ‘add new plugin’ I get this error in the dashboard. Twice!
I can download from the plugin list, but I cannot search for examples, ‘product search categories’ or simply ‘woo’ Any idea how to resolve?

Notice: Undefined property: stdClass::$plugin in /data03/c1496427/public_html/wp-includes/class-wp-list-util.php on line 150
