ERROR: GPU rendering in Dimension 4.0

Hello Dimension Community,

I installed the new Dimension 4.0 via the Creative Cloud 3-4 days ago. Since then I've been having the problem that I always get the following error message when rendering: ‘An error occurred during GPU rendering. CPU rendering was used instead’. But not only when rendering at the very end, even when I activate raytracing in the middle of the project (and therefore GPU rendering), this error message has already popped up. As a result, I have not yet been able to finish modelling a single project, let alone finally render it.

What I have tried so far:
1. on Windows 11 in the ‘Graphics Settings’ add dimension and set to ‘High Performance’ (Nvidia graphics card).
2. add dimension in the Nvidia Control Panel and switch to ‘Highest performance’ (Nvidia graphics card).
3. delete Dimension 4.0 via the Creative Cloud and reinstall it cleanly.

Nothing worked, although Dimension always recognises my graphics card on the first start and offers to select it to use GPU rendering. According to the error message, I should contact the community, so I hope someone here can help me out.

My graphics card: NVIDIA RTX A2000 Laptop GPU
Laptop: Dell Precision 5560
Dimension Version: 4.0

Thank you very much for any help!
Kind regards, Alex
