1) Open a Midi that starts before "0" in the timeline
2) MuseScore will crash instantly.

Instead, there should be a couple of detectors that scan the Midi before attempting to open it. Try to check for potential crash-inducing properties. Out of bounds, etc.

Regression No ⇒ Yes
Reported version 3.6 ⇒  

Works in MuseScore 1.3 BTW, it just imports it
But crashes already in 2.3.2, so a 2.x regression of sorts

This is an incorrect midifile. It doesn't open in Sekaiju or Cakewalk either.
I was able to open it with an old software. In it, it is seen that it started from the 23302nd measure.

As said: It does open, but does not play. Even if I woule wait 12hrs 56mins 42sec , it would not play, as Windows Media Play stops right away, as seen by the changes of the icon for Play and Pause. I can't 'fast forward' either.
