This block has encountered an error and cannot be previewed

Hello

I am having the same problem that many users are having:

"This block has encountered an error and cannot be previewed".

I have gone through all the threads you have open on the subject and tried everything: set another theme, deactivate plugins, I followed the advice on this page: https://docs.generatepress.com/article/debugging-tips/... I have tried everything but nothing works.

The funny thing is that it only happens to me with the heading blocks o Generate Blocks Pro.

In another WordPress installation something similar happened to me and I solved it by clearing Chrome's cache. But this time it doesn't fix it at all. It also happens in other browsers.

Thank you in advance
Regards
