If any game on Steam keeps crashing or shutting down without showing you any errors or Notifications, means the game files might be corrupted.

This happened to me recently with beat saber. After an update.

Go to the Game’s Properties by clicking on gear icon beside the game:

And click Properties.

Now go to Local Files and click “Verify integrity of game files…”

If game files indeed were corrupted due to some problems with the update, then you should see a message like in image above.

.. files failed to validate and will be reaquired.

Give it a few moments. Will depend on how many files were corrupted.

After this, hopefully the game will work fine now 🙂
