You may need to edit the permalink of custom post type.

By default, WordPress will not work Date-based permalinks of custom post type.

For example, a month link generates a link in a format like /<custom post type name>/date/YYYY/MM/, if you set Numeric in Common Settings in Permalink Settings.

The month link has the following two patterns depending on the Common Settings. But a link like below will not work.

• /<custom post type name>/YYYY/MM/ (Day and name, Month and name, Post name)
• /<custom post type name>/date/YYYY/MM/ (Numeric)

Recommend that you install the plugin in order to edit the permalink, if you are using a Date-based permalinks by the Widget.

And try the following:

Custom Post Type Rewrite https://wordpress.org/plugins/custom-post-type-rewrite/

Check the setting of the hierarchical argument of the register_taxonomy function.

hierarchical
(boolean) (optional) Is this taxonomy hierarchical (have descendants) like categories or not hierarchical like tags.
Default: false

Reference: https://codex.wordpress.org/Function_Reference/register_taxonomy

By hierarchical option,

If false, use "Tag Cloud (Custom Post Type)" as tags.
If true, use "Categories (Custom Post Type)" as categories.

Check the setting of the exclude_from_search argument of the register_post_type function.

'exclude_from_search' (bool) Whether to exclude posts with this post type from front end search results. Default is the opposite value of $public.

You can use the action hook custom_post_type_widgets/recent_posts/widget/prepend to adding thumbnails.

Code sample is as follows:

function cptw_hooks_setup() {
  add_action( 'custom_post_type_widgets/recent_posts/widget/prepend', 'cptw_recent_posts_prepend', 10, 4 );
}
add_action( 'after_setup_theme', 'cptw_setup_hooks' );

function cptw_recent_posts_prepend( $widget_id, $posttype, $instance, $recent_post ) {
  if ( has_post_thumbnail( $recent_post ) ) {
    echo get_the_post_thumbnail( $recent_post );
  }
}

Insert the above code into functions.php in your theme.
