Qubes froze during post-install setup


Today, I just installed Qubes 4.1.1 (R4.1) on a Thinkpad T440p.
While I succeeded in installing the OS, it just froze in the middle of the post-install setup.
As I write this, its stuck on “Installing Template Whonix-ws-16” and I can’t even move my mouse cursor about.

I did manage to install Qubes fine before on this machine with no problems.
The specs on my machine, currently, are a 250GB SSD, 16GB RAM and an i7-4800MQ CPU. No Nvidia GPU.

Also it’s been flashed with Coreboot with Tiancore as its payload and is plugged into a docking bay.
