I suspect the brake switch has failed.
try repeatedly stepping on the brake pedal and trying to shift car with key on. These switches fail a lot. The brake switch is located on the brake pedal and keeps the trans shifter locked until depressed.
Another way to try is to barely
rotate the key--keeping power off--sometimes you can get the shifter to release with the electrical power off. just have to play with it. If you get the shifter to release with power off, start the car in "neutral" then you can drive and get a new switch if that is the issue.
