Lots of people here have been saying that you should find a new job, which is probably not bad advise, but I do think you could also try to insist on boundaries more. If you don't set any, people won't respect them - it's often that simple.

You can compromise and agree on "core hours" where you'll always make yourself available, even if that's in the evening, as long as you can arrange for it. The company can compromise and adopt a more async style of communication (I've established that several times both in leadership and consulting roles - it works, you just need to know how to talk to C levels in their language.)

You could even give your leadership some weeks to come up with a solution, telling them your requirements (along with things you could compromise on). If they truly expect you to be available 24/7 - it'd be surprised, but that's clearly not a good place to work then. From my experience, this is the exception, not the rule.
