Cannot login after fresh install, missing SQL tables and welcome image

Installing ISPConfig 3.1 on Ubuntu Server 20.04 LTS, PHP 7.4, MySQL Ver 8.0.21-0ubuntu0.20.04.4 for Linux on x86_64

I'm almost done, but tried to log in with 'admin' and password provided during installation process but with no luck. The error message is as follows: "Username or Password wrong.1" Screenshot attached. Also, after installing ISPConfig I got admin login page without Logo image.

I followed over instructions how to change admin password with this command:

Code:

UPDATE sys_user SET password = md5('admin') WHERE username = 'admin';

but surprisingly it turned out the dbispconfig database does not have such table. In fact, the database is empty. I also attached screen with tables list. The connection between ISPConfig web app and the DB is established because there is a row created with info about login attempts.

Do anyone have an idea what's going on? The database seems to be corrupted. And why there is no Logo image on login page?

Here is my htf_report.txt file:
