Why does my D5 application/program crash?

Hi, please first test if you can open the default empty scene or any demo scenes without issues. 

- If the problem only occurs with specific scene files

Please refer to the solutions outlined in this post:

- If D5 Render is failing to open even empty or demo scenes

If D5 Render is failing to open even empty or demo scenes, it suggests a fundamental problem with your hardware or computer environment. Let's investigate these potential causes:

• Outdated or Corrupted Graphics Driver: Please try a clean installation of the latest recommended driver for your graphics card. You can find detailed instructions on how to do this here: How to view and upgrade graphics card driver? | User Manual
• CPU Overclocking Instability: If you've overclocked your CPU, try disabling the overclock to see if that resolves the issue.
• High Memory Speed (Above 4000MHz): If you're using XMP profiles that push your memory speed above 4000MHz, please try disabling XMP in your BIOS. Reducing the speed to below 4000MHz can improve stability. https://www.youtube.com/watch?v=h-MLhGMtheM
• Insufficient Power: Make sure your power supply unit provides enough power for all your components, especially under load.
• Loose Graphics Card: Double-check that your graphics card is securely plugged into the motherboard.
