Standalone Game crashes when loading level

Hi,
i recently added localization to our project and for testing purposes i need to launch our game in standalone mode. The game crashes every time it loads my main level. The loading screen still comes up, then crashes.
PIE works perfectly fine. Building the game works fine and the build itself as well.

The error states: *Assertion failed: BackBuffer->GetRefCo

Screenshot here, i hope you can help me out!

Cheers

I’m not really sure, but…

The problem seems to be when DirectX tries to resize the viewport. Aren’t you setting an invalid size by default somewhere? Like a resolution bigger than your screen, or too small…?

The latest lines (top ones) all have DX11 and Unreal function names like ResizeViewport etc. And, right after it (topmost), the assertion failed error. So it seems like something invalid was tried.

You are absolutely right, i had some leftover blueprints in my level blueprint, setting the resolution to something crazy…

Deleted it and it works perfectly fine :slight_smile: THX!

Awesome!! Glad I could help =)
