Error with new update: 2.9.2

I recently updated to version 2.9.2 and it has caused an error on my site. How can this be resolved? Is there a way to rollback to the old version?

The error is at the top of my page and where my create account button is:

“Warning: array_merge(): Argument #1 is not an array in /home1/yearlyonline/public_html/impact360/wp-content/plugins/elementor/includes/base/controls-stack.php on line 1184”

The page I need help with: [log in to see the link]
