Mission planner crash

After Updating mission planner to version 1.3.55 build 1.3.6660.28588

the app terminates after clicking on flight plan.
My Windows Log shows the following:

I have installed all Windows Updates and updated .net Framework via Microsoft page.
Uninstalled the Missionplanner removed the Programm Directory rebooted the machine installed it after downloading the app from Page.
I’m using windows 10 x64 with all updates installed.
