#Paragraphs

Debugging "This entity (paragraph: ID) cannot be referenced." Error
If you're encountering this error while editing content with Paragraphs, especially after changing paragraph type permissions, consider the following checklist.

- Go to: Structure → Content types → [Your Content Type] → Manage fields → [Paragraph field].
- Ensure the "Allowed paragraph types" includes all types currently used in your content.
- If uncertain, switch to "All paragraph types" temporarily to confirm if that resolves the issue.

Or

Check for Custom hook_query_alter() In my case issue was with this unwanted hook.
If you’ve recently added custom code using hook_query_alter() (or similar), it might be interfering with paragraph loading.

Example:

function MYMODULE_query_alter(QueryAlterableInterface $query) {
  // Check if this is affecting entity reference or paragraphs
}
