If you’re seeing the error UCEERR_RENDERTHREADFAILURE (0x88980406) when starting LaunchBox, it usually points to a problem with your graphics drivers or Windows rendering system.

🧠 What Causes This?

LaunchBox relies on your graphics card to render its interface quickly and smoothly. If your graphics drivers are outdated, corrupted, or Windows hits a rendering error during startup, it can crash the rendering thread in the background, resulting in this error.

🛠️ How to Fix It

1. Update your video card drivers

Go to your GPU manufacturer’s site (e.g., NVIDIA, AMD, or Intel) and download the latest drivers. In many cases, this resolves the issue immediately.

2. Run Windows Update

Occasionally, Microsoft fixes graphics-related issues via system updates. Make sure you’re running the latest version of Windows.

3. Restart your PC

It may sound simple, but a clean reboot can reset the rendering pipeline if something went wrong during startup.
