I'm been using Magento now over 4 years and each new update bring new issues. I'm at wits end with Magento the forum support sucks when you find a answer to your problem 50/50 shot it will work with your issue
Current issue now been working on since the update
Exception #0 (SodiumException): This is not implemented, as it is not possible to implement Argon2i with acceptable performance in pure-PHP

I did this yesterday, you need to go to WHM and type PECL in the search box, that will display Module Installers as the only option in the menu.
Software > Module Installers > PHP PECL
Search for Sodium (make sure you select the correct version of PHP from the drop down first) and try to install it.
If it errors then open Terminal
Server Configuration > Terminal
and run this command:
yum install libsodium-devel
Then go back and try again - that fixed it for me.
did all that and figured how the issue not thanks to Magento and lack of info
