Prerequisites

• I have carried out troubleshooting steps and I believe I have found a bug.
• I have searched for similar bugs in both open and closed issues and cannot find a duplicate.

Describe the bug

With the Gutenberg plugin installed (version 18.3.0 or later), the modal block editor (description field) in the new product editor crashes when the + (Add) button is clicked.

Seems to be caused by WordPress/gutenberg#61108

Expected behavior

The + (Add) button brings up the block inserter.

Actual behavior

The modal block editor (in fact, the entire new product editor) crashes, resulting in a blank page.

Steps to reproduce

With a WooCommerce env with the new product editor enabled (WooCommerce > Settings > Advanced > Features > Experimental features), and Gutenberg plugin (version 18.3.0) installed...

1. Go to Products > Add New
2. Click on Description > Full Editor to bring up the modal editor
3. Click on the + (Add) button in the header
4. Verify that the modal block editor (and new product editor) crashes, resulting in a blank page

WordPress Environment

Isolating the problem

• I have deactivated other plugins and confirmed this bug occurs when only WooCommerce plugin is active.
• This bug happens with a default WordPress theme active, or Storefront.
• I can reproduce this bug consistently using the steps above.
