Description
I get the same error. Whole bunch of sites. Looks like an infinite loop in a function that runs in the editor. I'm seeing a lot of people report the same error and bugs in Gutenberg since WP 6.3 was released.
Example messages logged in Console when a new block is inserted into a Gutenberg page, different sites:

This error and symptoms of this error have been reported by others in the WP forums and in Trac (See: https://core.trac.wordpress.org/ticket/59038)
Step-by-step reproduction instructions
- Load the Gutenberg Editor. Blocks show the 'Recover Block' error message.
- Add a new block into the editor. Console logs the error Uncaught RangeError: Maximum call stack size exceeded.
- Try to save a page. The page does not save.
Edits to pages can be saved only when the HTML editor is in use.
I've disabled and enabled plugins to try and discover whether the fault is being caused by a plugin. Apparently is not.
I've reinstalled 6.3 in 2 sites to see whether any files are missing. Made no difference.
The active theme is not the cause of the issue. the problem occurs in sites that use different themes.
I've tried to use Gutenberg with admin script optimizations disabled and with Jetpack Performance disabled. Neither attempt gave me a working editor.
Screenshots, screen recording, code snippet
No response
Environment info
I'm not using the Gutenberg plugin. I'm using the version of Gutenberg that ships with WordPress. I tried the Gutenberg plugin (latest) to see whether this would resolve the issue; it ddn't.
Please confirm that you have searched existing issues in the repo.
