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 RU2 MP1
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 versions of Google Chrome (chrome.exe) and versions of Microsoft Edge Chromium, Microsoft's Code Integrity feature is enabled. SEP Application Control technology is not compatible with this feature in Chrome/Chromium.
Please update to 14.2 RU2 MP1 build 14.2.5569.2100
If upgrading SEP is not an option, or the OS is one of those listed above, the incompatibility can be worked around by adding an Application Control exception for Chrome (Chrome.exe) and/or Microsoft Edge Chromium (MSEdge.exe).
Alternative options also include running Chrome with Code Integrity disabled:
Or by setting the following regkey value to 0:
Key: HKLM\Software\Policies\Google\Chrome Name: RendererCodeIntegrityEnabled Type: DWORD (32-bit) Value: 0
Note: If the regkey does not exist, create the registry key.
