Seeder doesn't like $filepath

[monstermaker]

I have created this in Laravel 7.4 and it mostly works, but when trying to seed the database with users it shows the following error:
getimagesize(): read of 8192 bytes failed with errno=21 Is a directory

If I die and dump $filepath just before the $getImageSize = getimagesize($filepath); I get the correct file path with the faker image shown at the end as a .jpg image:
"/home/vagrant/code/car_app/storage/app/public/user-images/2020/6/23/24541ee1986411e54cbcb0c8b80482a9.jpg"

Taking out the getimagesize() section and replacing with fixed data shows an error on the next call to $filepath which is '$img = Image::make($filepath)' and the error says 'Image source not readable'

I have tried replaced $filepath with the value of $filepath (storage_path('app' . DIRECTORY_SEPARATOR .
'public' . DIRECTORY_SEPARATOR .
config('project.user.images_folder') . DIRECTORY_SEPARATOR .
$date->year . DIRECTORY_SEPARATOR .
$date->month . DIRECTORY_SEPARATOR .
$date->day . DIRECTORY_SEPARATOR .
$main_image_name)) directly and then it shows the issue as being the $main_image_name part.

When I run the seeder it does create some images in the correct sub folder in storage and also creates the three sizes in the correct sub folders in public/uploads. Sometimes there is one image created and sometimes 2 or 3 but it gets no further than this.

Maybe this is a timeout issue?
