Description

This crash happens to ~ 10 % of our users and can especially be seen on old device where users want to open a window which is already being pushed. The core-side solution is to check the navigation VC stack before and ignore the call in that case. The client side workaround could be to set a flag to block new window pushes before the window is opened.
