Sounds like some linkage came loose from the shifter... At the very least a shifter problem.

Take a good luck at what goes on with the inhibitor switch when the shifter is moved. The inhibitor switch would prevent start but probably because it isn't rotated properly, not that it is defective.

I think it is moved mechanically with the shifter, so not moved to one of the start positions is a clue. Wouldn't think it is a big problem to check out and get going... Sure hope not!
