Hi folks
I have a drupal 8 project with a broken block definition/configuration or something similar. So i can't use the entity reference field with blocks, because this error appears if drupal wants to show me all available blocks in a field widget or something (e.g. node edit form) for example:
The website encountered an unexpected error. Please try again later.

I don't know why i have a Broken/Missing block, and i don't know which block that was before that happens, because i don't miss any block.
At first i thought the error disapperars with resaving the admin page (block layout) ( https://www.drupal.org/node/2744823 → ). But i was wrong. The error is still there.
If i use this code:
$block_manager = \Drupal::service('plugin.manager.block');
$definitions = $block_manager->getDefinitions();
dpm($definitions);
The definitions has a broken array:
If i comment out the exception (line 53 of core/modules/block/src/BlockPluginCollection.php), the node edit form loads and i can see this:
Sorry for not more information about reproducing this error. But i don't know why this error appears.
With a new drupal installation, everthink works fine. But somehow i get this error now and i can't reinstall drupal with the current procject.
Question: What can i do to repair this?
And maybe this is a bug which caused all.
