Database error when attempting to log into an account which exists - Table 'wikidb.oathauth_users' doesn't exist

[userapache123]

I am using in Windows server:
MediaWiki 1.35.2
Apache 2.4.47 Win64 from Xampp
mysql-8.0.23-winx64 (MySQL :: Download MySQL Community Server)
PHP 7.4.3

I have sucessfully created a new account in wiki. After that, I get a page as:

Your account has been created. You can change your aocwiki preferences if you wish.
Return to Main Page.

By clicking on "Main page", I can successfully edit the Wiki page. 

After that, I log out.

Next, when I attempt to log in using the same account (which was created only a few minutes back) and I know the password, I get the error as:

A database query error has occurred. This may indicate a bug in the software.

As this was related to the upgrade of Wiki, I had to upodate PHP. Doing the PHP update using the information below solved the problem.
