There is a known issue with Google Chrome 78 that causes the browser to be unusable. You will not be able to access the settings or any webpage.
According to google “There is a known incompatibility between Chrome Renderer Integrity and old versions of Symantec® Endpoint Protection® (14.0.3929.1200 and earlier). We recommend updating to the latest version of Symantec Endpoint Protection (14.2 or later). For a download of the latest version or more details, refer to the Symantec documentation. To help with any incompatibilities, you can temporarily disable Chrome Renderer Integrity using the RendererCodeIntegrityEnabled policy.”
Workaround 1: Load google chrome in Windows 8 compatibility mode
- copy google chrome icon to the desktop
- right click on it then choose properties
- go to the compatibility tab
- choose windows 8
Workaround 2: Disable Chrome Renderer Integrity
Chrome Renderer Integrity is on by default for users on Microsoft® Windows® 10 version 1511 and later. It prevents unsigned modules from loading in Chrome Browser’s renderer processes that deal with user content to prevent certain types of malicious attacks.
For Symantec® Endpoint Protection users: Upgrade to version 12.2 or later
