PHP Fatal error: Uncaught TypeError: Cannot access offset of type string

I have been going through our error logs as our server has been crashing on occasion due, at least in part, to this site.

[01-May-2023 11:42:23 UTC] PHP Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /home/user/public_html/wp-content/plugins/wpforms-lite/includes/fields/class-name.php:527

This error tends to show up just before our server crashes.

Any help would be greatly apprecieated.
