After thousands of attempts at new installations via prestashop upload, softaculos via cpanel, php changes, and everything, after each new installation of prestashop 9, it gives me the following error in the backend admin panel and I can't access it

That error usually shows up when there’s a PHP or module conflict. Try enabling debug mode in Advanced Parameters → Performance to see the real error message. Clear cache (/var/cache/prod) and check recently installed/updated modules or theme overrides
 

please send the screen after enabling febug mode to be able to help.

well let's not do it 1001 times, prestashop installer works very well, try this:

o Download PrestaShop

https://github.com/PrestaShop/PrestaShop/releases

Choose the release you want: the latest stable version of PrestaShop 8 or the new PrestaShop 9 package.  Note 9 is new, you may be better off with 8.2.2 but it's your choice of course.  

o Check PHP compatibility

Look up which PHP versions are supported for your chosen PrestaShop release, and make sure your hosting environment matches.

o Set PHP version on your hosting

In your hosting control panel (cPanel is clunky — if possible, request Plesk in the future), set the correct PHP version for the domain you’ll be installing on.

o Upload PrestaShop files

Upload the ZIP file you downloaded directly to your domain’s root folder.

o Unzip the package

Extract the contents of the PrestaShop ZIP into your domain folder.

o Create a database

In your hosting panel, create a new database and user. Make note of the database name, username, and password — you’ll need them during installation.

o Run the installer

Visit your domain in a browser. The PrestaShop installation wizard should appear. Follow the on-screen instructions to complete the setup.
