After removing a WordPress domain in Plesk WP Toolkit starts to show an error: Can not find domain by id X

After removing a domain with a WordPress instance, an error message starts to appear on the Plesk Panel:

Can not find domain by id 123
Email notifications from Plesk may be received by domain owners about application updates:

Updates were not installed for the following items:
1. Instance "My Instance Name" (https://example.com): Can not find domain by id 123
An attempt to remove a plugin from another WordPress instance fails with:

Installation "example": Can not find domain by id 123"
An execution of the Plesk Daily Maintenance task on Linux shows a similar error:

# /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php
...
ERR [panel] pm_Exception: Can not find domain by id 123
The following records can be found in the Plesk log files /var/log/plesk/panel.log on Linux or %plesk_dir%adminlogsphp_error.log on Windows Server:

Failed to generate screenshot of instance #5: URL of instance #5 is empty
ERR [extension/wp-toolkit] Can not find domain by id 123
Unable to remove WordPress instance via Applications. The following message is returned on a blank page:

{"status":"success"}
The WordPress instance files were manually from /var/www/vhosts/example.com/httpdocs.

Orphaned data in WordPress SQLite database for the removed domain

Apply the corresponding steps:

Connect to the Plesk server via SSH.
Create a backup dump of the 'psa' database.
Remove any possible tasks leftover from the Plesk database:

# plesk db "truncate longtasks"
# plesk db "truncate longtaskparams"
Create a backup of the WP Toolkit database:

# cp -p /usr/local/psa/var/modules/wp-toolkit/wp-toolkit.sqlite3{,.backup}
Access the WP Toolkit database in SQLite:

# sqlite3 /usr/local/psa/var/modules/wp-toolkit/wp-toolkit.sqlite3
Enable headers:

# sqlite> .headers on
Get a WordPress instance ID using the domain ID from the error message. In this example, domainId is 123:

# sqlite> select instanceId from InstancesDomains where domainId=123;
instanceId
567
Remove all corresponding information:

# sqlite> DELETE FROM Instances where domainId=123;
sqlite> DELETE FROM InstanceProperties WHERE instanceId=567;
sqlite> DELETE FROM InstancesDomains WHERE instanceId=567;
sqlite> DELETE FROM Instances where id=567;

Note: If more than one instance id was listed on the previous step output, execute the above InstanceProperties, InstanceDomains and Insntances deletions for each ID number accordingly.
Exit SQLite:

# sqlite> .quit

Connect to the Plesk server via RDP.
Download the command tool for managing SQLite databases and extract sqlite3.exe into %plesk_dir%varmoduleswp-toolkit.
Create a backup of the 'psa' database.
Open a command prompt (CMD) as Administrator and remove possible tasks leftovers from the Plesk database:

C:> plesk db "truncate longtasks"
C:> plesk db "truncate longtaskparams"
Create a backup copy of the WP Toolkit database:

C:> copy "%plesk_dir%varmoduleswp-toolkitwp-toolkit.sqlite3" "%plesk_dir%varmoduleswp-toolkitwp-toolkit.sqlite3.bak"
Open the downloaded tool and access the WP Toolkit database:

C:> "%plesk_dir%varmoduleswp-toolkitsqlite3.exe" "%plesk_dir%varmoduleswp-toolkitwp-toolkit.sqlite3"
Enable headers:

sqlite> .headers on
