Adding any texture files while the IPR is running will crash Arnold GPU

[520200178]

Hi there, the issue is basically this: if I try to add, for example, an EXR file to a Skydome/Arnold sky, Arnold will crash immediately if I have the IPR running in GPU mode. The crash can be reproduced with shaders too, if I try to add a texture file to an "Image" node it will also crash Arnold if I have the IPR running.

Note this only happens in GPU mode and only if I have the IPR running. If I disable the IPR, add the texture files, then run the IPR, it will work without issues.

Setting the "fallback" to CPU doesn't prevent the crash.

I'm using C4DtoA 2024 4.6.7.1 and NVIDIA Driver 551.23.

C4D crash report is attached if you want to look into it

Thanks!
