Apps from Mac App Store crash when started (CODESIGNING error)

Today I reinstalled macOS High Sierra on my MacBook Pro (Mid 2010). Now all apps I install from App Store crash immediately when being started (e.g. Pages, Numers, Bear, ...). Apps with a installer from the web still work, as well as all the apps coming with macOS itself.

This is what the report says:

Error report

I tried reinstalling macOS once again, I "repaired" the system SDD ... problem persists.

Any solutions?

MacBook Pro 13″, macOS 10.13

I just tested, and yes, it works after reboot. Only need to run the script for every app after installation.
