Stuck after upgradation

Hello folks

i've been working with Akaunting and got stucked after upgradation from 1.3.17 to .18-200-208, after facing problem with php version, I found that could not restore it from a valid backup .sql that I have, even with a fresh 1.3.17 install.

I need a guide to step back, I got a functional .sql database but I am not sure how I can restore it bcz justing rolling back the database still does not works...

You need to run at least PHP 7.3..

That`s right... I am running PHP 7.4

# php -v
PHP 7.4.5 (cli) (built: Apr 19 2020 08:42:37) ( NTS )

The logs are not telling me much... I probably messed up by trying restore my database before backing up the /var/www/html~akauting-directory

Anyone know how to restore it? most probably needs php + artisan tools to do so, but I am not familiarized with these

I managed to rollback, still I can not upgrade, if I do the application brokes...

Tried to upgrade again and after upgradation its stops at step 3rd - could see an error 500 being generated

Actually I continue having access to it, I am still able to login, change pages.. However the upgrade page generate this errors:

Trying to get property 'data' of non-object (View: /var/www/html/akauntingdir/resources/views/install/updates/index.blade.php)

After executing php artisan update:db

I've loaded the new page layout, but now I face this:
