Same thing for me too…:
PHP Fatal error: Class ‘ParagonIE_Sodium_Compat’ not found in …/wwwroot/wp-content/plugins/wordfence/vendor/paragonie/sodium_compat/lib/constants.php on line 6
Very strange because the “vendor/paragonie/” folder no more exists in the v7.3.3. How can I have an error from a file that does no longer exists?
Other strange thing, I have 2 of my websites totally broken with the v7.3.3 and all others (15+) who seems to be working fine but with that same error appearing in the log file.
Is there a load balancing problem somewhere?…
