HI @muhammad_shoukr ,
Give the following permissions to the magento directory and try.
sudo find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \; && chmod u+x bin/magento
sudo chmod -R 0777 var/ pub/ generated/
All make sure that .htaccess is exist on the magento root folder.
I hope it will help you!
