Multiple virtual hosts with Apache in live development server, Laravel 9 PHP Fatal error: Uncaught RuntimeException: A facade root has not been set

[trxSuperAdmin]

I have a dev server that is used by me and a fellow dev, I have set up similar scenarios on live development servers before. The following Apache set up has worked on other Laravel projects, though lower versions.

The set up:
Server version: Apache/2.4.57 (Ubuntu)
PHP 8.1.18 (cli)
Laravel 9.19
React 18
Inertia 0.8.1
vite v3.2.6

There are 3 working directories, dir1, dir2 and dir3. In the apache conf files the following virtual host conf is enabled, {ip} omits the real IP addresses.

Apache virtual hosts file:

Listen {ip}:81
Listen {ip}:82

<VirtualHost *:80>
    ServerName {ip}
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/dir1/public
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    #RewriteEngine on
    #RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]

<Directory /var/www/dir1/public>
    Require all granted
    AllowOverride All
    allow from all
    Options +Indexes
</Directory>

</VirtualHost>


<VirtualHost {ip}:81>
    ServerName {ip}:81
    DocumentRoot /var/www/dir2/public

<Directory /var/www/dir2/public>
   Require all granted
   AllowOverride All  
</Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>


<VirtualHost {ip}:82>
    DocumentRoot /var/www/dir3/public

<Directory /var/www/dir3/public>
   Require all granted
   AllowOverride All  
</Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

The working directory (dir1), serves and presents the application fine, dir2 and dir3 both through the same apache log error

I have ran every cache clear command known to me, including the all singing all dancing php artisan optimize:clear

I've ran composer:update, npm run build, all to continue to get the same error each time.

I have ran this exact same Virtual host set up before in other Laravel 8 projects with even more ports and directories and have copied the exact same structure so the issue lies with the framework itself, however, I can't narrow down the root cause as to why the application will not run on multiple ports
