The app crashes and exits by itself when clicking on the "Exchange" feature

Project Information

Repository : https://github.com/KredsBlockchain/kreds-core/
Title : Kreds Wallet
Publisher : Kreds Blockchain

Expected behavior

Supposedly, when I click the "Exchange" feature the app will not get into error and will not exit by itself.
And if the feature has not been activated, then it should be when the user clicks on the feature, then the feature can not be opened and does not crash. Different as I found out.

Actual behavior

When I open the app and accidentally click the "Exchange" feature, the app suddenly crashes and exits by itself.

How to reproduce

1. Install and open the app
2. If you are already on the app home page, click on the "Exchange (Disable)" feature located on the three-line menu.
   Next you will find the error as I experienced
