If there's an engine start-up issue with a rocket late into its maglev launch, failure changes from "unload the propellants and try again tomorrow" with a vertical rocket on a pad to "yeeting an out of control rocket and its valuable payload into whatever is downrange".

Couldn't you have two tracks? One track for cancelling late and one for yeeting? If the mission gets cancelled then it goes into a slowdown track loop, if the mission does not then it gets yeeted.

Probably, but that just adds even more to the cost, construction time, and land area needed for each launcher complex.

All said, maglev launchers on Earth are just an impractical solution that don't really solve any of the real problems with chemical rockets. Basically every problem with chemical rockets launching from Earth that is solved with a maglev launcher can be solved way cheaper and way faster by just designing rockets to carry a little more fuel.
