Description (last modified by SergeyBiryukov)

This is related to ACF Pro, but didn't happen until the upgrade to WP 5.5. I downgraded to 5.4.2 to make sure and I can verify it's a WordPress issue, likely related to REACT or the Rest API. I don't know enough about the Gutenberg editor to know if it's specific to that, so I'm posting here with "second-opinion" Workflow Keyword.

I have several custom blocks created using ACF Pro. One of them requires multiple javascript files and uses the "enqueue_assets" attribute to enqueue them.

When I try to edit any post, I get a popup error that covers the entire screen saying "The editor has encountered an unexpected error." and has 3 buttons: "Attempt Recovery", "Copy Post Text", "Copy Error". None of the buttons work.

In the console, I get these errors:

TypeError: First argument must be a String, HTMLElement, HTMLCollection, or NodeList

    at G.hasOverflowedContent (components-1480.js:24)
    at G.fitTitle (components-1480.js:24)

After the second error, the first error repeats and keeps getting hit every few milliseconds, telling me it has thousands of times within a minute.

I'll post this with ACF Pro, too, but wanted to mention here in case it's a WordPress bug. I don't know how many people use ACF blocks in the Block Editor, but it completely prevents people from editing posts if they have some.
