v3.39.0 breaks build with nested blocks

[lunacd]

Describe the Bug

When using nested blocks, v3.39.0+ fails build with

Error occurred prerendering page "/". Read more: https://nextjs.org/docs/messages/prerender-error
TypeError: Cannot read properties of undefined (reading 'columns')

v3.38 and before have no issues.

Important bits in the reproduction:

• The nested block:
  https://github.com/lunacd/romantic-austin/blob/a5bea92878a331809d664eb3ecc513cd00ca56df/collections/NestedBlock.ts#L1-L16

• A collection that uses the nested block:
  https://github.com/lunacd/romantic-austin/blob/de1122eaaaee4a623b801095ddd106bfa30bd48c/collections/Collection.ts#L10

• Use the collection in any manner:
  https://github.com/lunacd/romantic-austin/blob/de1122eaaaee4a623b801095ddd106bfa30bd48c/app/(app)/page.tsx#L8-L10

If:

1. the block is not nested (see https://github.com/lunacd/romantic-austin/blob/de1122eaaaee4a623b801095ddd106bfa30bd48c/collections/Collection.ts#L11-L12), OR
2. the block is not used (delete https://github.com/lunacd/romantic-austin/blob/de1122eaaaee4a623b801095ddd106bfa30bd48c/app/(app)/page.tsx#L8-L10), OR
3. payload v3.38 is used instead

This issue does not happen.
