Try running sfc /scannow in command prompt. If you have any NordVPN or Malwarebytes product installed try disabling them. Also try a different DNS provider.
Already tried SFC and Dism to see if there are any problems and both show no issues.
Don't have a VPN or Malwarebytes installed.
Tried DNS provided by my ISP and also changed it to Google 8.8.8.8 / 8.8.4.4 and Cloudflare 1.1.1.1 / 1.0.0.1
Don't have an offline key as this is for Lifetime/Premium Plus users only and I'm only Lifetime.
Still same issue no change.
Thanks.
