Backup uploaded and extracted, but at 99% of DB restoration, I am getting errors while WP migrating (plugin "All-in-one-migration")

I created an EC2 instance and installed PHP, MySQL, Apache and WordPress. I configured the below four files:

1. sudo vim /etc/php/8.1/apache2/php.ini

   • Change maximum file size upload limitation.

   • Upload_max_filesize, post_max_size, max_execution_time, max_input_time, memory_limit and max_file_uploads

2. sudo vim /etc/apache2/apache2.conf

   .htaccess by (<Directory /var/www/> AllowOverride All)

3. sudo vim /var/www/html/wp-config.php

   Set you DB credential and define('FS_METHOD', 'direct');

4. sudo vim /etc/ssh/sshd_config

   Set password authentication

How can I resolve this issue?
