I tried this 3 times and got the same out come. I'm not sure if this is my computer or what but every time I die on round 3 I get a black screen and that's it. I've killed myself on purpose, I let him kill me on the last shot, and I let him do all of the damage. I assume this is because of the update that came out today.
Also I tried it on my steam deck and still got the black screen, so it's not my computer it is a bug.
(probably reinstallation wasn't even needed, but i won't be able to check that now)
. But I think it was because you guys patched it, not that it was my drivers being outdated.
