Laravel, Unknown error after deploying to LIFE server, 500 Internal Server Error

I just deployed a Laravel 8 project from my local server to a LIFE server and apparently everything works fine, I successfully run Composer( composer update), composer throws no error messages, the LIFE server's domain is linked to the folder /project/public. I also It ran successfully php artisan migrateand I can see the tables created by artisan in the database, so the application is connecting correctly with the database.

I also changed the permissions of the main project folder to 755 and the permissions of the storage folder to 777.

sudo chmod -R 777 ./storage
sudo chmod -R 777 ./bootstrap/cache/
sudo chmod -R 664 /mainprojectfolder

I successfully generated a new KEY with artisan, and successfully cleared the cache with artisan... That is to say, I have read all the tutorials I found on the Internet, but the problem has not been solved.

php artisan key:generate

I also managed to clear the project cache, as suggested by the official documentation:

php artisan config:cache
php artisan route:cache
php artisan view:cache

I also created the .htaccessfile:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

When I browse the server URL, I see that the browser redirects to domain/login correctly, which is correct, as long as I'm not logged into the app it redirects to the login page. Then the browser shows the classic:500 Internal Server Error - The server encountered an internal error or misconfiguration and was unable to complete your request...

Unfortunately, I don't have access to the server logs, as the server is a shared virtual server, so I can't figure out what the problem is.

Can you recommend it?
