Page and Post edit page not loading

Hi!

I’m facing strange problem. After installing Rank Math SEO plugin I’ can’t access edit page for posts and pages.

What I’m using:
Wordpress 5.1 with Themosis Framework (https://framework.themosis.com/)
Rank Math plugin v1.0.20 (tried out 1.0.17 and got the same error)

Here is notice that is being displayed:

Notice: CMB2_Field::__construct() was called with a parameter that is deprecated since version 2.2.3! Using the “default” field parameter as a callback has been deprecated in favor of the “default_cb” parameter. in /Applications/MAMP/htdocs/pl.dawidwozniakowski/htdocs/content/plugins/seo-by-rank-math/vendor/cmb2/cmb2/includes/CMB2_Base.php on line 456

I have no other related php or Apache errors.

UPDATE:

After updateing plugins settings I get this exception, and dashboard is not loading (same error as above but now thrown as exception)

ErrorException (E_USER_NOTICE)
CMB2_Field::__construct() was called with a parameter that is deprecated since version 2.2.3! Using the “default” field parameter as a callback has been deprecated in favor of the “default_cb” parameter.

Thanks in advance!
Chris
