Call to a member function bundle() on null in social_group/src/Plugin/EntityReferenceSelection/SocialGroupSelection.php

I'm having the same issue with 10.0.4.
I've enabled layout builder module. Then I set up the landing page content type to use it, added and deleted sections and blocks to my landing page. The issue occurs when I revisite the manage display page.
The patch #2 seems to solve the issue.

Here is the full error message:

The website encountered an unexpected error. Please try again later.
