I'm having this exact issue as well with my desktop. Both ethernet and normal Wi-Fi say no internet access, but clearly it works since I'm typing this on it. Tried updating Windows 11 from 22H2 to 23H2, but that didn't work. I also don't have Norton or use a VPN period so that isn't the issue for me. Thankfully most of my software for university classes work still, but not having the Microsoft Store working still sucks. I built this desktop back in July so it's frustrating that it's having this issue now.
EDIT: I also tried using an external Wi-Fi adapter, same issue. Works completely fine on my old desktop.
