I am trying to:

Add a new post in a custom post type created with toolset.

Link to a page where the issue can be seen:
It is the admin page when you click add new.

I expected to see:
The block editor.

Instead, I got:

The editor has encountered an unexpected error. I tried disabling all plugin and switching to the 2023 theme and it still had the same error.

I clicked the copy error and I get:

TypeError: Cannot read private member #e from an object whose class did not declare it

Hi there

Although the symptoms appear slightly different, this looks like a variant of this known issue: https://toolset.com/errata/wordpress-6-5-update-breaks-editor-if-using-core-media-block-with-dynamic-sources/

We hope to be in a position to release a fix soon, and in the meantime the best workaround would be to downgrade WordPress to 6.4.4, as described in the linked page.

Thank you! I reverted and that solved it.
