Whitelist the .exe in Defender or any other AV that might interfere with it.

I did add C:\Program Files (x86)\Steam\Steam.exe to the exclusion list within Microsoft Defender and no luck. Also attempted to download with firewall turned off.

Turns out I managed to fix the issue myself, though I feel a bit silly about it. My time was synced correctly, but the date wasn’t. Once I got both the date and time aligned, the installation went through without a hitch. Sorry for the false alarm and thanks again for your help!
