I am encountering an error whenever I want to use this block it says “This block has encountered an error and cannot be previewed.”

I updated the content click update and then refreshes the data remains the same.

If this block is present on the page then that page’s content is not updating no matter how hard you try and after removing this block everything working fine.

A page on one of our web sites recently started showing errors in the block editor. After extensive testing, I discovered that disabling the Testimonial Block plugin fixed the problem. Of course, the testimonials block on the affected page stopped displaying the way we want, so I had to re-enable it, and the errors in the block editor returned. We’re using WordPress 6.3.1, which I guess is not yet supported by this plugin. Using the latest Astra theme.
