All paths (CachePath, BrowserSubProcessPath, etc) must be absolute paths, if using a non-absolute path an exception will be throw. See #3102 for details.
When using a RequestContext you must ensure that RequestContextSettings.CachePath is equal to or a child of CefSettings.RootCachePath See https://github.com/cefsharp/CefSharp/issues/3111#issuecomment-629713608 for details
Starting in June 2019 Google will block logins from CEF based browsers to Google Services, this includes Gmail, Drive, Docs, see https://security.googleblog.com/2019/04/better-protection-against-man-in-middle.html?m=1 for further discussion see https://groups.google.com/a/chromium.org/d/msg/embedder-dev/STyM5ZNTHMM/POj1v_cqBgAJ
