PHP Error – Unable to use the plugin

Hey there,
We use the Organic Builder Widgets Pro (Version 2.1.14) on our website. We noticed that we can no longer use the plugin while editing/adding the pages on our site. For example, if we want to remove the Slider from the homepage and we go to Page Editing Screen, we see no blocks or settings related to Organic Builder Widgets which used to be working totally fine about 2 weeks back.

Then we noticed the error logs and found a lot of similar entries:

2020/09/26 17:55:03 [error] 34629#34629: *1116 FastCGI sent in stderr: "PHP message: PHP Warning: array_search() expects parameter 2 to be array, null given in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1905PHP message: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1919PHP message: PHP Warning: array_search() expects parameter 2 to be array, null given in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1923PHP message: PHP Warning: array_search() expects parameter 2 to be array, null given in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1905PHP message: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1919PHP message: PHP Warning: array_search() expects parameter 2 to be array, null given in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1923PHP message: PHP Warning: array_search() expects parameter 2 to be array, null given in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1905PHP message: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/lensofjen.org/htdocs/wp-content/plugins/organic-widgets-pro/admin/widgets/class-organic-widgets-custom-widget.php on line 1919PHP message: PHP Warning: array_search() expects parameter 2 to be array, null given in /var/www/lensofjen.org/htdocs/wp-content/plugi

Kindly, help us out to fix this issue so that we can edit the pages on our site and add the new ones using your plugin.
