Scrolling arrows

As of this morning I can no longer use my arrow keys nor my PageUp PageDn functions to navigate websites using the Dissenter Browser. These keys work fine on other programs including other browsers. I’m using the browser on an iMac using the latest version of Monterey. The browser version is Version 0.70.122 Chromium: 78.0.3904.87 (Official Build) (64-bit). Home and End keys are not responsive either.

Is there a reason these keys have stopped functioning altogether?
