Hello @Jaworskyj,
Thanks for writing in! It seems that you are simply having come caching issues. After doing the updates, always remember to clear all caches (if you are using Autoptimize, WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
And please clear your browser cache too. You may use private browsing mode in testing your site to make sure that you are viewing the latest codes from the updates and not the cached version in your browser.
It could also be caused by a plugin conflict, amongst other things. Please check out this troubleshooting article here and follow the instructions for the following sections (where appropriate):
