MAKE SURE YOU HAVE A DB BACKUP

You can verify that your admin_user_session table has the primary key set to auto-increment with this query:

SELECT `AUTO_INCREMENT` FROM  INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA 'magento_db' AND TABLE_NAME = 'admin_user_session';

If you see that auto-increment is turned off, then you can fix it with this query:

ALTER TABLE 'admin_user_session' MODIFY COLUMN 'session_id' INT NOT NULL AUTO_INCREMENT;

However, if you need to do that, that is a good indication that either your DB import failed or you have some custom functionality with admin sessions that is blocking the auto-increment functionality.
