Self hosted Invoiceninja 4.5.32 installation not working

Guide I followed for the installation:

Installation guide

Im currently trying to install Invoiceninja on Ubuntu and im getting the following error during composer install:

@php artisan package:discover

In Container.php line 752:

Class LaravelCrawlerDetect does not exist

When I look into the apache error.log I get the following when trying to load the site:
[php7:error] [pid 9242] [client] PHP Fatal error: Uncaught ReflectionException: Class view does not exist in /var/www/html/invoiceninja/vendor/turbo124/framework/src/Illuminate/Container/Container.php:752


Maybe the info here will help:

Already tried that solution, but still the same.

It may help to use the selfhost zip or use v5 instead.
