Answer 1

It may occur after some time after you set up your new system.

As a suggested solution, just try on Windows

1) open cmd.exe as Administrator

2) run mysql_upgrade.exe -uyour_user_name -pyour_password

mysql_upgrade.exe can be located at

C:\Program Files\MySQL\MySQL Server 8.0\bin

Then run the following to see if the infoschema user has appeared.

select user, host from mysql.user;
