Thanks for reaching out. Could you please try below steps:

1. Clear Google Home App Cache & Data (Android)

For Android users, clearing the local cache and data of the Google Home app can sometimes force a refresh that eliminates the broken link.

Go to your phone's Settings.
Navigate to Apps (or Applications / App Management).
Find and tap on the Google Home app.
Select Storage (or Storage & Cache).
Tap Clear Cache, and then Clear Data (or Clear Storage).

Warning: Clearing data will log you out of the Google Home app and may remove local settings. You'll need to log back in and re-set up any voice match or other personalized settings, but your main "Home" and devices should remain.

2. Unlink the Service Directly in the Google Home App

Try unlinking the service one more time, as sometimes it works after a delay or a fresh app launch.

Open the Google Home app.
Go to Devices - Add - Works with Google Home
Find the entry for your old project (e.g., [test] Your Action name) under Linked services.
Tap the service name, and then tap Unlink account (or Remove).

If this fails with a "Couldn't check your connection" or similar error, proceed to the next method.

3. Remove Third-Party Access via Google Account Security

This method targets the access token granted to the deleted project, which may be the persistent element.

Go to the Third-party apps & services page in your Google Account security settings. You can find this by searching or navigating to: myaccount.google.com $\to$ Security $\to$ Your connections to third-party apps & services $\to$ Your action name $\to$ Delete all connections you have with the action.
Agree to Remove access.

After removing access, open your Google Home app and try the "Unlink service" step again (Method 2), or say the voice command "Hey Google, sync my devices."

4. The "Create & Delete Home" Workaround (Last Resort)

If all else fails, a known community workaround involves creating a new temporary Home and deleting it, as this sometimes forces a deep refresh of all linked services.

Open the Google Home app.
Create a new, temporary Home (give it a name like "TEMP DELETE").
Go to your primary Home (if the ghost device is only there), or stay in the new Home.
Try to move the ghost device/service to the new "TEMP DELETE" Home (if it appears as a device tile).
Once the ghost link/device is in the "TEMP DELETE" Home, go to the Settings for the "TEMP DELETE" Home.
Scroll down and select Delete this home.

This process often cleans up all orphaned or "ghost" devices and linked services associated with that temporary Home. You may need to wait a few minutes and restart the Google Home app afterward.
