The submitConfigurationForm method in the BlockContentBlock class does not include the : void return type, which causes a fatal error due to a mismatch with the parent class BlockBase. This issue occurs when updating from Drupal 10 to Drupal 11 with php 8.3
block_content module enabled.drush updatedb or interact with blocks that use the BlockContentBlock plugin, in my case the block_post_update_set_menu_block_depth_to_null_if_zero trigger the issue .Add the : void return type to the submitConfigurationForm method in the BlockContentBlock class to ensure compatibility with the parent class BlockBase.

Can you share what patches you are running for core on your site?
You are right :) I am using a patch for reusable blocks that add that code.
Thank you
