Can't install .NET Framework 3.5 (error code 0x80070490)

Question

Hello

I'm trying to install .NET Framework 3.5 on Windows 11, but getting error code 0x80070490 no matter if the installer is offline or online version. I reset all network as well and tried different Wi-Fi and Wi-FI hotspot that go though my phone to 3G but it still won't install and give me error code 0x80070490. Uninstall anti-virus and dsiable firewall doesn't solve the problem.

I've used the control panel, downloaded the instaler manualy but i can't install it on my pc.

Same error code (0x80070490) when it's downloading on the Method 1 – Using Turn Windows features on or off

On Method 2 – Using Windows Terminal after the command says
