Update: I got it working!... I saw a post about mouse stuttering somewhere and they posted back saying another program was interfering with the mouse. The only thing I had running was my antivirus/firewall... so I shut it off to test and immediately had mouse movement. I've set the game as an allowed application and I'm able to play normally now.

I have the same issue with the same symptoms as Kass and Merc noted. Middle-click is recognized and my cursor works in the menus. Mine is from Steam (just released yesterday... with DLC) and not Epic Games. However I have had this game installed on this machine from the Epic Games before (few months ago... without any DLC). I've noticed that the keybindings for "look up/down/left/right" are not set. Reset to default doesn't bind them either. If I bind the keys to something like numkeys, I can look around fine afterwards (with those keys)... but how do I manually set mouse movement to those? I'm assuming it's not DLC or launcher related... but it's possible. I've been looking at forums for the past day and not many people have this issue. No one on Steam seems to have this issue either. I have a logitec wireless mouse (I can't test with a wired mouse unfortunately) 4k screen resolution (tried fullscreen and windowed in 4K and 1080 with vsync on and off since I saw a post that resolution can bug the mouse) My old saves were still there, but I wasn't able to look around with my mouse either when I loaded those. I created a new char (save when landing) and no dice.
