Nodes suddenly gone, only the node author stay in the admin/content page

Can you check the node table in your database and the node_field_data table

I think I've seen this before if you delete your node types

this is the node/node_field_data table, I have not deleted the node types, they are still showing on the admin/structure/types page without problems.

What code or configuration changes to the site preceded this?

I can't remember exactly, I installed the "Content Moderation Notifications" module which require the workflow and Content Moderation both module installed, I was play around the workflow to publish and unpublish the nodes, maybe I was deleting some nodes, then suddenly happened.

There have been no updates in eight months.
