By copying the complete wamp64 folder, there will be no information in the registry and the updates and additions of versions will be impossible.
You have to install Wampserver in the exact same path as before the crash and eventually add the Apache, PHP, MySQL and MariaDB versions that were used before the crash.
And only then restore the VirtualHost folders of wamp64/www/, the httpd-vhosts.conf file and the data folders of MySQL and MariaDB.
