Does wp_safe_redirect() no longer works?

Question

Inside index.php I used wp_safe_redirect to redirect users to the main global page if users write a false url.

I have 1 domain and three subdomains. These subdomains refer to php files and not to child themes or multisite.

    $Subexplode = explode('.', $_SERVER['HTTP_HOST']);
    $SubName = array_shift($Subexplode);
    $A = 'domainname';
    $B = 'subdomain1';
    $V = 'subdomain2';
    $H = 'subdomain3';
    
    if($SubName === $B || $SubName === $V || $SubName === $H){
        $redirectUrl = '/reception';
        if(is_home()){
            header_remove();
            wp_safe_redirect($redirectUrl);
            exit;
        }
    }

WordPress auto php analyse refuse, inside theme files editors, from Tuesday 10 Jan to validate php file with fatal error : "Unable to send a message to the site to check for fatal errors."

wp_safe_redirect('/') is the only function/line that interrupt wordpress analyse and validation file during update theme files.
