I would stake out some boundaries. Stop working weekends, say no to the unscheduled work sessions, or don't answer the phone/slack/whatever. Personal time is yours. Ignore the toxic behavior, it's not about you, it's their problem. The worst that can happen is you get let go, which is where you are now anyway. In the meantime look for a better job -- much easier to get a job when you already have one.
