Error Logging Into Magento 2: Open Source admin panel

SO I followed instructions here:
https://www.thecoachsmb.com/6-steps-to-install-magento2-4-2-on-xampp-windows-using-composer/

to install Magento 2 into a fresh install of xammppv3.3.0 running Php7. Once its time to get into the Admin account, It first said the information was incorrect or locked. I ran the commands

(php bin/magento admin:user:unlock <username>)
and
SET @salt = MD5(UNIX_TIMESTAMP());
UPDATE admin_user SET password = CONCAT(SHA2(CONCAT(@salt, 'NewP@ssword'), 256), ':', @salt, ':1') WHERE username = 'adminusername';

• all commands came back successful. The I recieve the following:
  Error processing your request

So i look into the log and see the following message:

main.CRITICAL: This is not implemented, as it is not possible to

According to all searches ive done, this is due to sodium not being used in my PHP, but it is:

the ‘;’ in front of sodium in my php.ini is removed, but I still cant get into magento admin. Any help?
