Thank you for the screenshot, your Intel WiFi drivers are not installed correctly.
On another device that has an Internet connection, like the one you are accessing this forum with, go to the support page for your Pc on the manufacturers website, then from there, download the installer for the Intel WiFi (WLAN) drivers they provide, then transfer that installer to your PC and use it to re-install the Intel WiFi drivers.
I also see you have Express VPN installed, it may be a good idea to temporarily uninstall that until the network problems are resolved.
