When trying to register a user, after submission you are redirected to a 500 server error

Problem: When trying to register a user, after submission you are redirected to a 500 server error, but the query to the database, meaning the insertion of the new user is successful.

Actions Taken:

Deactivated All Plugins
Renamed .htaccess file
Deactivated all Block Content in M2 and All Add-on Modules
Reset .htaccess by saving permalink structure
Tried a redirection function using the registration_redirect hook
Tried a redirection function using the login_redirect hook

Not sure what is going on. GL Team!
