[BUG] Can't open

[Xriqxa]

I click on US2, a window opens, flashes, then closes. If I open it anywhere on Steam it works, though, albeit a bit of nuisance to go to Steam every single time.

I don't think logs are necessary here, but tell me if you need them.

If you don't open through Steam this is what happens... Universe Sandbox ² loads, launches Steam if it's not running, closes, and reopens via Steam.

Is it closing and not automatically reopening?

[Xriqxa]

Steam is open when this happens.

Is Universe Sandbox ² closing and not automatically reopening?

So I click on it, it opens a small window in the top-center of my screen, flashes white, closes the window, quits US2, and that's it.

Did you try the verify integrity of game cache thing anyway

No; what is it?

This is how you verify the game cache of a Steam game.
