How to understand "assertion failed" crashes?

Hi! I recently got a crash warning, that I’m trying to solve. It happens when I boot up a packaged game for the first time.

I can’t seem to understand what the issue is. All I have done since last time the packaged game worked, was making a movie intro for the game.

How does one find out/debug these kinds of crashes?

Edit: So after some debugging, i found that the new movie file I have added has been causing the crashes. But its strange that it is, because the movie is not supposed to be used right as it boots up the game.

Seems I found the issue!

It was related to using “Async Loading Screen”. There is a bug at the moment where if you add more paths to the “startup movies” array, it crashes the game.

Hope this helps someone else1 :slight_smile:
