This is 2022. If your house was wired in the past 20 years, most electrical problems are caused by some anomaly, and rectified by turning a switch back on, or, at worst, unplugging an offending appliance. I know. Been there, done that.
So, if you don't feel confident to flip the switch back on and can't get an electrician to show up for 2 weeks (not unusual), perhaps you have a neighbour that has some expertise in that field?
