Sorry you are having all the issues. Do you have a VPN (virtual private network), if so try and disable. if your not sure  you can see if you have a VPN. When connected, the VPN connection name will display Connected underneath it. To see if you’re connected to the VPN while you’re doing things on your PC, select the Network icon (either  or ) on the far right of the taskbar, then see if the VPN connection says Connected.
