Issue with portable text causing crashes in Sanity Studio 3.29.0

Hi, I have a problem with portable text in Sanity Studio 3.29.0. In Sanity Studio 3.24.1 I don’t encounter this issue.
Whenever I add a block array (copied and pasted from docs) my structure tool crashes. In fact, the document either does not load or returns this error:


Error: Maximum call stack size exceeded
RangeError: Maximum call stack size exceeded
    at getRandomValues (<http://localhost:3333/node_modules/.sanity/vite/deps/chunk-G7CAILKR.js?v=ca194635:107199:19>)
…
My schema looks like this:

export default {
  name: 'pageNotFound',
  title: '404',
  type: 'document',
  fields: [
    {
      title: 'Bild',
      name: 'image',
      type: 'image',
    },
    {
      title: 'Überschrift',
      name: 'headline',
      type: 'string',
    },
    {
      title: 'Absatz',
      name: 'paragraph',
      type: 'string',
    },
    {
      name: 'content',
      type: 'array',
      title: 'Content',
      of: [
        {
          type: 'block'
        }
      ]
    }
  ],
}
As soon as I remove the block array the document loads again and the error disappears. Does anybody know how to fix this?

Hey I have the same issue for some reason – did you find a solution?

Can you share an example of the content you’re pasting in?

I've got this same issue too, just upgraded everything Sanity related to latest.

Block content defined like so in my schema...

...
defineField({
      name: 'byline',
      type: 'array',
      of: [
        {
          type: 'block',
          styles: [{title: 'Normal', value: 'normal'}],
          lists: [],
          marks: {
            decorators: [
              {title: 'Strong', value: 'strong'},
              {title: 'Emphasis', value: 'em'},
            ],
          },
        },
      ],
      title: 'Byline',
      description: 'Page introduction, appears below the title',
      group: 'settings',
    }),
...

I used:
export default {
	title: "Content",
	name: "normal",
	type: "array",
	of: [
		{
			type: "block",
			styles: [{ title: "Normal", value: "normal" }],
		},
	],
};
