macOS App Store download crashing with EXC_CRASH (Code Signature Invalid)

I'm seeing a released macOS App Store app crashing with a code signing error.

This isn't a beta app, it's been signed by Apple and is available on the App Store.

On most systems it installs and runs fine (macOS 10.15, macOS 11 on Intel, macOS 11 on Apple Silicon etc.), but on 10.13 we see a code signing error.

This is a Network Extension app. It crashes as soon as the mgmt app is opened, before any load is tried on the Extension.

We haven't been able to determine whether this error is widespread or not, but it seems like something that should never be happening with an App Store installed app.

The app was uninstalled and reinstalled from scratch, and the error persisted, and the MacBook Pro was rebooted. Still happened.

Any ideas? The existing discussions around this error were for beta/development builds, which isn't applicable here.

Hi kjbrock,

Do you have any update on this?
I'm facing a very similar issue with my app (which is a regular app, nothing fancy, distributed through App Store): it seems to work fine on most of the systems, but one guy using 10.13 reported me that the app is consistently crashing at startup with "Termination Reason:   Namespace CODESIGNING, Code 0x1" . I also have a one star app review which is hinting at a similar problem.
