Ok, I will check that and if any query/help needed then i will inform you.
I will try it because as i check functionality of contact us page, The contact-us page does not use the email template. It uses mail design from contact-us module.
For errors some of the code issue are generated again because of the updates. Error like the contact us page issue was generated because of the deprecation of the php function in php8.
And for brand listing i will check that.
