Can you try temporarily disabling your antivirus and see if the trainer runs.
Google this and there's quite a few hits:
MEA STUCK ON LOADING SCREEN GETTING ON TEMPEST
Here's one answer I saw:
No matter what players have been doing, they can’t seem to find a way to continue their progress in Mass Effect: Andromeda once they hit this error on the loading screen. Currently, there doesn’t seem to be any idea as to what causes it, and unfortunately, there’s no way to get past it either. For now, you’ll just have to completely exit out of the game and restart it. This does come with the unfortunate risk of losing some progress. Fortunately, Mass Effect: Andromeda tends to save before you hit a loading screen, so you really shouldn’t be affected too badly.
