How It Affects Your App
The impact of MySQL 1720 ER_PLUGIN_NO_UNINSTALL on an application is that it prevents the plugin from being uninstalled. This can cause the application to become unstable and unable to function properly. It can also lead to data loss or corruption, as the plugin may be required for the application to run correctly. In addition, it can cause the application to become slow or unresponsive, as the plugin may be taking up resources that the application needs to run.
How To Fix

$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:

3. Check the MySQL process list to see if any processes are running that could be causing the error:
$ mysqladmin -u root -p processlist
4. Check the MySQL user privileges to see if any users have been granted too many privileges:
$ mysql -u root -p -e "SELECT User, Host, Password FROM mysql.user;"
5. Check the MySQL database tables for any corruptions:
$ mysqlcheck -u root -p --all-databases
6. Restart the MySQL service to apply any changes made:
$ service mysql restart
