Why would Kakashi bee doomed , do you think with your head ? Or with your butt? Kakashi has warped himself to that dimension what makes you think he can't warp himself out? He has kamui man smh

kakashi didn't warp himself to kamui by himself. .. yet. , but he did warp himself out.

I find that Manga-Stream translation are more reliable. However, both mean the same thing. Panda says he can't use Kamui anymore and Manga-Stream implies it. Obito thought he still had the Intangibility-Ability in his arsenal and got hit so he's telling himself to be more careful because he can't be as reckless seeing as he can't phase through things anymore.

not quite. not being able to use Kamui on yourself is different than being reckless..
saying you cant be reckless simply means don't let your guard down, (because u have so much power) don't get sloppy.
it doesn't necessarily mean he cant use kamui anymore... but looking at things you could draw your own assumptions.
