Windows 10 Search, Cortana, and Edge crashing

I’m having an issue with the Start menu search function and MS Edge. Here’s what happens:

Search: Staff A hits the windows key and types in “outlook” (for example…). The search box gets 1, maybe 2 letters in before it locks up completely, turns black, then closes.

Edge: Staff X clicks on the Edge icon to open it up. Edge opens with two tabs that immediately say “This page is not responding” then shuts down immediately.

Following all the steps to reset Cortana, searchui, or edge result in no change of behavior.

Also, if you open a website shortcut and Edge is the default browser, the web page opens with no issues on Edge. The issue only occurs on the default error pages such as if there is no available internet connection or Edge’s default homepage. But whatever, I don’t even care about Edge. The issue I’m concerned with is SearchUI.exe crashing.

Here are the error messages I’m getting in the event viewer for SearchUI.exe and subsequent information message. The faulting module is the same as the faulting module for the Edge error message.

Can anyone help? Besides downgrading to Win 10 17xx and going through several release upgrades, does anyone have insight? This application is critical to business processes, unfortunately. (Can’t wait until the new software is completed!).
