Rewriterule on hostinger doesn't work. I tried by both redirecting it through the site manager & editing the .htaccess file as well

WROTE THIS CODE INORDER TO GENRATE A CLEAN URL BUT DOESN'T WORK NEITHER
REDIRECTION THROUGH SITE MANAGER(HOSTINGER) WORKS.

    RewriteBase /
    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^Branch([A-Z])$ semester.php?br=$1 [L,QSA]
