Hi @harish_padala

As you have changed your database name from magento_demo to magentodemo , same way you need to change this name into your env.php file

So go to your magento 2 root directory -> then app directory -> then etc directory -> over there you will find env.php file

In this env.php file , you will find below array parameters 

 array (
        'host' => 'localhost',
        'dbname' => 'magento_demo', // you need to change your new name over here
        'username' => 'root',
        'password' => 'root',
        'active' => '1',
      )

From here you need to change your database name with the new name !

You can also find this error from magento 2 root directory -> var directory -> report directory

Over there you will find file name - 1643579333

open this and check error log and post over here if issue is not solved !

but your issue will surely changed once you change your database name into the app/etc/env.php file

Hope it helps
