When launching Google Chrome version 78.0.x or later, the message “Aw Snap! Something went wrong while displaying this webpage.” is present if any version of Symantec Endpoint Protection (SEP) is installed with the Application Control feature on Windows Server 2016 or Windows 10 RS1. This issue also affects Microsoft Edge Chromium version 78.0.x with an error message of “Page cannot be displayed”.
Chrome and Chromium are also impacted when installed on any Operating System (OS) with a SEP version older than 14.2.
In the Google Chrome browser:
Aw Snap! Something went wrong while displaying this webpage.
In the Microsoft Edge Chromium browser:
Page Cannot be displayed.
In version 78.0.x of Google Chrome (chrome.exe) and 78.0.x of Microsoft Edge Chromium, Microsoft’s Code Integrity feature is enabled. SEP Application Control technology is not compatible with this feature in Chrome/Chromium.
Alternative options also include running Chrome with Code Integrity disabled:
Or by setting the following regkey value to 0:
Type: DWORD (32-bit)
Or install an older version like Chrome 76
Or Chrome.exe –no-sandbox
