Iray stuck on 'warm-up' with RTX 5090 – only works with CPU enabled

Hi,
I recently upgraded to a new ASUS RTX 5090, and I’m experiencing an issue with Iray in the latest version of Substance Painter.
All system and GPU drivers are fully up to date

    Iray does not work on the RTX 50 series cards. This is likely not a bug but rather intended.
