How to solve the error "Microsoft Dynamics NAV Client has Stopped Working"

Hi All,

I'm using the Navision 2017.

I faced this error after some changes in Sales Order(42). In the Home tab of the Sales Order Ribbon there have a action group "Liberer" and there have two action "Release and Reopen" But the Reopen action does not working properly that's why I replace the Reopen action from the "Liberer Action Group" with the Reopen action from "Release Action Group" of Action tab of the Ribbon by using the Ribbon Customization.

After that I faced the error "Microsoft Dynamics NAV Client has Stopped Working" when I try to Open Sales Order Card Page From the Sales Order List Page(This Page Open Normally).

Kindly Give some solution if you have....
