Artisan giving PHP Fatal error

Hi,

I'm not sure what happened. My app has been fine, and as far as I know I didn't change anything, but when I ran composer update it threw this error:

  - Removing fideloper/proxy (dev-master 5f70b1d)
  - Installing fideloper/proxy (dev-master 30988aa)
    Downloading: 100%         

Writing lock file
Generating autoload files
PHP Fatal error:  Class 'Fideloper\Proxy\ProxyServiceProvider' not found in .../site/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 157

Script php artisan clear-compiled handling the post-install-cmd event returned with an error

Now, if I try to do anything at all with php artisan, I get

PHP Fatal error:  Class 'Fideloper\Proxy\ProxyServiceProvider' not found in .../site/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 157

I also get the error if I try to run composer install or composer update now. No error is thrown if I run composer install --no-scripts or composer update --no-scripts however, but this still doesn't fix Artisan.

I've tried clearing composer's cache, removing "fideloper/proxy": "dev-master" from my composer.json file, and changing "dev-master" to "3.0.0", but I'm still stuck. Any ideas?

Thanks!

My composer.json is as follows:
