I dug into this. My guess is that the user account somehow became linked to a non-existing entry so it would no longer link to any other entry — which is exactly what you want normally.

Stuff I did to diagnose.

Installed the following plugins

• User Switching
• User Meta Display

Added a new Code Snippet to support linking when using the User Switching plugin.

This allowed me to remove the user meta which was linking the user account to a non-existing entry.
Once that was done, I could use User Switching to switch to the user to verify the it linked correctly, which it did.

I’ve left these excellent tools installed for your use. You can delete safely if you wish.

Apologies for the trouble.

ps. Delete the user account and adding it again would have resolved the issue too.
