Is this the most recent Kingdom Come 2? I’d been thinking of getting it myself

No, first one. 2 has not been released yet.

Kingdom Come Deliverance. Low fantasy, no map marker (in hard mode), no superhumans or anything too fancy…

Can you access your wan ip when you are somewhere else than on your own lan?

If not, then this is probably just that your router does firewalling and nat is such order that you can access admin interface from local network via wan address.

If yes, then router has some serious misconfiguration.

Also check your bios version. I had similar problems with usb-c and fans on HP Elitebook, they were fixed with bios upgrade.

Edit: I also had troubles waking from sleep. They were caused by wwan/lte modem, I disabled it on bios and now sleep works flawlessly.

For first-time Linux users, I always recommend one of the main user friendly distributions - it is much easier to ask or look for help this way.

So, Fedora, Ubuntu or Opensuse.

Their installers all can live boot

Blog makes valid point, but why on earth there would be any current Linux distribution without usr merge?

EDIT: Especially when every major Linux distributions have already implemented usr merge long time ago.
