Windows 10: Windows 10 Activation error 0x800705b4

I can not get my windows to activate. I keep getting this error. I am also not able to get Windows to update. And I can not get computer to change sign in to a microsoft account. This is a Lenovo Desktop that Lenovo sent a tech to change the motherboard out back in the middle of 2020. I just saw it was not activated now. I have tried to do a stand alone upgrade with the latest Windows 10 ISO. It failed also
