Electrical – I have a flooded basement and have an electric cord plugged into an outlet. How to unplug the cord without getting shocked

It is possible that you have a bad outlet before the freezer. Many times contractors use the push in connectors on the back of the outlets called "stabs" (I think they should be outlawed). These knife edge connections don't do well with loads like freezers because they draw a large starting current. Start by checking the outlets close to the one that powers your freezer since you just replaced that outlet. There are usually several outlets on the same circuit the problem could originate from a working outlet that the load side stabs failed. I work my way back to the first working outlet on that breaker check it, then check the next one that is dead. It has been this almost 100% of the time. I have repaired well over a hundred over the years Only 1 or 2 had loose wires at the breaker and there one that the outlet was covered with sheet rock. If you don't find it you may need to hire an electrician that has a through the wall scanner to find breaks behind the walls with a tool like a Greenlee CS800 but these are expensive and not something a home owner would use very often.

I'm assuming you are in the United States for this answer. A stove is normally on a dedicated circuit which means it alone is the only load wired to a particular circuit breaker. This means nothing else would have been affected if your stove's breaker tripped. The breaker for your stove will be larger than a normal 120V breaker in your panel so you would have had to reset this if the breaker indeed tripped. If your stove was still on, resetting the breaker may have been difficult; the switch may have been difficult or impossible to switch to the "ON" position.

I am assuming you unknowingly reset the breaker when you were switching things in your breaker panel. If you are certain you didn't, then you may have never actually tripped a breaker and have some other electrical problem.
