Alternative Fixes

Alternative options also include running Chrome with Code Integrity disabled:

  • Run Chrome.exe (with the Windows Run app or via Mac OS Terminal) with this command: Chrome.exe --disable-features=RendererCodeIntegrity 
  • On a Windows machine, set 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.
