Substance Designer won't launch

[NaoYuee]

After updating my old substance designer to the newest version 15.0.3 Substance designer is unable to launch. When I do so it stays stuck on the splash screen. I have tried multiple solutions but it does not seem to work.

The solutions I have tried:

• uninstalling and reinstalling the app (version 15.0.3 and version 15.0.0)
• launching the app as admin
• updating my Nvidia drivers to version 581.57
• Changing my graphics processor to high-performance in the Nvidia control panel
• Disabling my Nvidia GPU (seemed to work, at first, as it opened the software and my graph but crashed a few seconds after opening)

My specs:

• Laptop model: Acer Nitro AN517-41
• Processor: AMD Ryzen 7 5800H with Radeon Graphics (16CPU)
• Operating System: Windows 11 Home 64-bit version 25H2
• 16GB RAM
• DirectX 12
• Nvidia GeForce RTX 3050 

I have found multiple threads with the same issue however I still haven't found a way to solve this problem. Is there anything I might have missed ? 

Thank you for your help !

Hello @NaoYuee,

Thank you for your message.

We've indeed received messages from different users facing crash at start up since the 15.0. Although we have some leads, we still don't understand exactly why the crash is occuring (yet).

It's possible that the integrated GPU is bringing all the trouble, even if it isn't used for running Substance Designer. Therefore, I strongly advise you to also update the integrated GPU (Radeon Graphics in your case), and let me know if it helps.

Best regards,

I had the same problem,

See this post here

Cleaning the internal GPU Drivers and once starting Designer with the internal GPU worked for me.

All the best Marco
