Would it be an isekai if there's time travel but for some reason some of the characters personalities change from the original timeline?
To me it would depend on how different the new timeline actually is, but probably not. If the only thing thats different are some characters and maybe which businesses are successful, I wouldn't consider it an isekai. Something like an alternate history version of the present like where the other side won WW2 or aliens invaded or something like that would probably be enough for me to count it, but it really is a vibes thing to some degree.
It's kind of interesting how almost every genre/theme descriptor heads down this path. Originally it's strict, but as time goes on things merely similar get lumped in and the definition softens and becomes vibes based, potentially morphing into something entirely different. Like RPGs which at this point are only tangentially related to playing a role with continual agency in a story. Can blame JRPGs for the start of that shift.
