Paragraph Blocks don't seem to work with Layout Builder Browser

Problem/Motivation

This module doesn't seem to work with the Layout Builder Browser module. Not sure if the issue is on Paragraph Blocks end or on Layout Builder Browser end. If Paragraph Blocks module is enabled, I can't add any blocks whatsoever into Layout Builder Browser and get JavaScript errors in the console. If I don't have Paragraph Blocks enabled, I can add blocks freely to Layout Builder Browser.

This is the error I'm getting in the browser console in Firefox:

Uncaught 
Object { message: "\nAn AJAX HTTP error occurred.\nHTTP Result Code: 200\nDebugging information follows.\nPath: /admin/config/content/layout-builder-browser/blocks/add?blockcat=my_components\nStatusText: OK\nResponseText: ", name: "AjaxError", stack: "@http://MY-DOMAIN.com/core/misc/ajax.js?v=9.5.10:92:32\n@http://MY-DOMAIN.com/core/misc/ajax.js?v=9.5.10:642:3\n" }

I'm also getting this error in dblog which may be related:

Error: Call to a member function getPluginId() on null in Drupal\paragraph_blocks\ParagraphBlocksEntityManager->getRefererEntity() (line 93 of /home/username/MY_DOMAIN/web/modules/contrib/paragraph_blocks/src/ParagraphBlocksEntityManager.php)

Steps to reproduce

1. Install Paragraph Blocks and create paragraphs on a content type as needed to be exposed as paragraph blocks.
2. Test that the paragraph blocks are working within Layout Builder correctly.
3. Install Layout Builder Browser via Composer/Drupal UI.
4. Go to /admin/config/content/layout-builder-browser/categories and create an initial block category.
5. Go to /admin/config/content/layout-builder-browser and click the "Place block" button next to your block category; nothing happens. Check browser console for error message.
