Elements broken in Guttenberg editor

I’m using the built in editor with UB but now whenever I edit a page with a UB element or try to add a new UB element to any page, the element shows very briefly then is replaced with “This block has encountered an error and cannot be previewed.”

This is only happening with UB elements, other plugin elements are working fine. I first noticed the issue today but I don’t edit the pages very often.

i’ve tried using the version control to put UB to an earlier version but that made no difference.

If I view the page, the elements load and work fine, only in the editor the problem exists, but that means I can’t use/edit the elements.

Thanks for reporting the issue.

I apologize for the inconvenience.

Can you please provide some more information?

Like what version of WordPress you are using, list of theme and plugins you are using.

That will help me to recreate the issue on my end and come up with a fix soon.

Please let me know.

Kind regards.

Same issue. All the latest of everything. WP 6.2.  Did not update to Gutenberg 15.7 as it doesn’t reporting being tested with 6.2.  Would appreciate any help. I have used your blocks extensively, and they seem to render fine where used, but are no longer editable, and I cannot use them on new pages or posts.
