Error Message & Unable to Edit Certain Blocks

Hello,

We’re getting error messages on certain blocks in the backend of our website: “this
block has encountered an error and cannot be previewed.” The frontend of the website displays correctly. Trying to view or make internal edits within the blocks is the issue. The affected blocks in our site are accordion, buttons, tabs, expand, etc.

I’ve pasted an example screenshot below and included a link to the page.

Can you provide guidance on this? Will reverting to an older version of Ultimate Blocks work?

WordPress Version: 7.1
Ultimate Blocks Version: 3.6.0
