I had an issue where starting the game causes it to automatically minimize and then be unopenable.

Here's a fix I discovered.

1. Set your monitor's resolution to 1024x768.
2. Launch the game -- it should start now.
3. In the game's graphics settings, set the resolution to your monitor's native resolution (e.g. 1080p). The game will minimize again automatically.
4. Set your monitor's resolution to what you just chose in the game settings.
5. Click back into the game and it should work.

It seems the game's default is 1024x768. If your monitor's resolution doesn't match the game's resolution then it keeps minimizing itself.

Hopefully this helps someone else.
