A common problem (I am not sure how common, but there are hundreds of reports) with the Edge browser in Windows 10 is that it gets into the habit of opening and then immediately closing, or closing when you try to browse the web.

I was trying to fix a PC with these symptoms. In the event log, an error was logged “Faulting module name: EMODEL.dll.” Among much useless advice out there, there is one that has some chance. You can reinstall Edge by following a couple of steps, as described in various places. Something like this (though be warned you will lose ALL your Edge settings, favourites etc):

Delete C:\Users\%username%\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe (a few files may get left behind)

Reboot

Run Powershell then Get-AppXPackage -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose}

However this did not fix the problem – annoying after losing the settings. I was about to give up when I found this thread. The culprit, for some at lease, is IBM Trusteer Rapport and its Early Browser Protection feature. I disabled this, rebooted, and Edge now works.

Failing that, you can Stop or uninstall Rapport and that should also fix the problem.
