Turn off Sandbox mode
Google Chrome makes use of a Sandbox mode to provide the best possible protection against malware threats. It does so by creating a single process per tab, which helps to contain the malware issues (if any) within that process. But this method can consume a lot of resources from your computer and cause the Kill Pages error to appear. You can fix this issue by turning off the sandbox mode, which will, however, reduce the security of your web browser.
In order to do that, you can add -no-sandbox as an argument when launching Chrome. Simply right-click the Chrome shortcut you use the most, and go to Properties. At the end of the Target text box, enter -no-sandbox after the closure of the double quotations.
