Go to Multi PHP manager and choose PHP8.1 for your wazone admin panel subdomain.
If this is not working, then will need .htaccess edit to bypass the default php version used by your domain globally.
The syntax will be slightly different from server to server, so would be best if you create a ticket to your hosting provider to ask how to edit .htaccess to force php8.1 on wazone admin panel site.
