Problem/Motivation

When editing a paragraph type, an error related to Entity Usage appeared, so attempting to uninstall the module also resulted in an error.

The website encountered an unexpected error. Try again later.

The Entity Usage module depends on the Paragraph library and Paragraphs Demo modules.
Uninstalling Paragraphs Demo followed by Paragraph library succeeded without error.
However, the following error ultimately appeared, preventing the uninstallation of Entity Usage.

The website encountered an unexpected error. Try again later.

As a Sunday programmer, I relied on Google Antigravity for a solution and successfully uninstalled it.
I've attached the workthrough for reference.

Entity Usage Uninstall Fix Walkthrough
Summary
The entity_usage module failed to uninstall due to a PluginNotFoundException caused by attempting to load definitions for entity types from already uninstalled modules (specifically paragraphs_library_item).
I patched entity_usage.module to check for the existence of an entity type definition before attempting to retrieve it during the uninstall process.

Changes
Fixed entity_usage_module_preuninstall
In web/modules/contrib/entity_usage/entity_usage.module, I added a check using EntityTypeManager::hasDefinition properly handle missing entity types.

foreach ($source_entity_types as $key => $entity_type_id) {
    // Added check:
    if (!$entity_type_manager->hasDefinition($entity_type_id)) {
      unset($source_entity_types[$key]);
      continue;
    }
    // ...
    $entity_type = $entity_type_manager->getDefinition($entity_type_id);

Verification
I verified the fix by successfully running the uninstall command:

ddev drush pm:uninstall entity_usage -y
Result: [success] Successfully uninstalled: entity_usage

The module has been successfully uninstalled.

Thanks for the bug report. I can see that we should harden this code. Taken a slightly different approach from AI but the result is the same.
