BrowseWithPMService does not work on macOS Sierra

[Mannes]

I am running Photo Mechanic Version 5.0, build 17719 and I run Mac OS X 10.12 on my Intel-based Mac.

I noticed that the BrowseWithPMService does not work anymore.
Also when using the option key no dialog appears to select the application.

Here the log info:

We have tried to reproduce your problem on two macOS Sierra equipped computers and have been unable to reproduce the problem.

Do you have some sort of extensions installed that modify the behavior of the file open dialogs or any other aspects of the system?
