Hi and welcome to WordPress Core Trac!

This probably belongs in the support forums, and the Localhost Installs forum already has a topic about the error.
​https://wordpress.org/support/topic/wordpress-fatal-error-uncaught-error-failed-opening-required-failed-to-open/

The topic recommends upgrading PHP to get the native sodium_crypto_box() function. Another topic recommended ​trying a manual update to correct a different 'No such file' error, and that could be good to make sure you have all the files.
