Application Export does not work for bigger Projects SC 9.0.0007

I am trying to export all my application in my project.
This works for smaller projects with up to 50 applications. One of our bigger project has over 250 applications.
When I try to export them all at once I only get a blank screen (only menu buttons are displayed)

I can export the whole project via Project->Export though.

What is the difference between exporting a project and exporting all application of a project?
The exported file for projects is much smaller than for all applications.

I am afraid something is missing if I only export via Project tab. Please fix this! :wink:

Hello,

Any error occured? The environment is from our installer or is a manual environment?

As I said I only get a blank screen. No error message is displayed :frowning:

We run a manual installation on ubuntu:

PHP: 7.0.20-2~ubuntu16.04.1+deb.sury.org+1

Diagnose has no errors except some missing db connectors.
