OIDN crashes Blender 3.4.1

[Epicalert]

When rendering with OpenImageDenoise Blender crashes, but in the viewport it works fine. Also thanks for keeping LuxCore alive!

.blend file: Default project

Steps to reproduce:

1. Open Blender
2. Switch Render Engine to LuxCoreRender
3. Enable Halt condition and Denoise with OIDN
4. Render

Screenshots or rendered images: N/A

Error message from Blender console:

I can reproduce this here - tried debugging and can't find anywhere obvious, the same problem doesn't happen in luxcoreui or luxcoreconsole, or with denoising off.

I'm testing with this blender file: (with the halt conditions turned down to 10-20 instead of 2000, but it doesn't seem to matter, it's just quicker) https://github.com/LuxCoreRender/LuxCoreTestScenes/tree/master/scenes/UnderwaterPaintings

With API logging turned on, I get the following output:
