TypeError: Cannot access offset of type string on string in date_views_filter_handler_simple

I have updated my site to PHP 8.0 and I'm still getting this error despite having the latest release of date.

TypeError: Cannot access offset of type string on string in date_views_filter_handler_simple->accept_exposed_input() (line 150 of /var/www/html/docroot/sites/all/modules/date/date_views/includes/date_views_filter_handler_simple.inc).

I get the error anytime I'm trying to edit any node that includes a date field.
