IRAY Render doesn't work after new GPU

So my old GPU stoped working (Geforce RTX 4070 ti) and I got a new GPU (Geforce RTX 5070 ti)  I did a clean install of the driver.

But when I try to IRAY Render it doesn't work. Render screen remains empty.

My build is 4.24.

In the log it says:

2025-10-23 20:46:04.903 [WARNING] :: \src\pluginsource\DzIrayRender\dzneuraymgr.cpp(373): Iray [ERROR] - IRAY:RENDER ::   1.0   IRAY   rend error: Cannot render: found no usable devices. Please update your NVIDIA driver (www.nvidia.com) to at least 537.13, or enable CPU rendering.
2025-10-23 20:46:04.903 [ERROR] Iray :: Invalid parameters (NULL pointer).

But I have: 581.57 Nvidia Studio Driver.

    Daz Studio 4.x cannot support the version of iray needed for the 50x0 cards - you will need to use the Daz Studio 2025 Alpha for rendering, though you can still do scene set-up in DS 4 (third-party plug-ins and some scripts are not working in DS 2025, and will need updates/new versions to do so - if the developer is still active).
