It seems that the Cornerstone plugin is not installed properly, I would suggest your use FTP and go to the wp-content/plugins —>delete the cornerstone directory.
Now please make sure you have updated the X theme properly or I would suggest you follow the below steps while updating to the latest version of the theme.
Download the fresh copy of the X theme from the Themeco dashboard
Activate the WordPress default theme
Delete the X theme
Install the latest version of the X theme
After the X theme is updated, use the link in the dashboard to automatically install the Cornerstone. It will be at the latest version.
I would also suggest you troubleshot a few common issues on this.
Please make sure your PHP version is 7.4 or 7.4+ as per our version compatibility page. It is also recommended by WordPress as well.
If you have not seen the theme update doc please have a look at it.
If none of those work, It would be best if you could copy your live website to your staging area. and send your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details
WordPress Login URL
Admin level username and password
FTP Details
You can find the Secure Note button at the bottom of your posts
