Cannot run any object from Development Environment After cumulative update 8 NAV 2016

I recently installed cumulative update 8 for NAV 2016 and I have

- compiled all the objects with 0 errors
- I can run the role tailored client without any issues.
- I have restarted the service, server and SQL.

But When I try to run any object from Development Environment Table, Page, Report, XML Port I get an error

Microsoft.Dynamics.NAV has stopped working
