.blend file: any, screenshot has the default cube scene which gets created upon opening blender.

Steps to reproduce: (Parenthesized steps mean pre-steps, which are probably not necessary. Bold steps are the main steps.)

(-Have older Windows, older than the newest build as of writing this.) (-Download+install BlendLuxCore normally, using the zipped version.) -Have Windows 11 (Home) on version 22H2, build 22621.1848 -Download+install BlendLuxCore normally, using the zipped version from https://github.com/LuxCoreRender/BlendLuxCore/releases/tag/latest) -Open blender -Set the render engine to LuxCoreRender

Error message from Blender console: OpenCL driver API error (code: -1, file:D:\a\1\Luxcore\src\luxrays\devices\ocldevice.cpp, line: 89): CL_DEVICE_NOT_FOUND

Additional information: It all worked fine before windows updated my machine. It stopped working after windows updated. The viewport display this message, as well as the render window. Cycles, Eevee & Workbench work just fine. I don't have a D: drive and if I connect an external drive, it is D:, but there is no such folder as the one mentioned in the error message. I have never (in the time of using LuxCore) used a different external drive than that one. Kinda off topic, but Visual Studio Code Insiders also stopped working after the update, so it probably isn't just LuxCore related.

OS: Windows 11 Home, build 22621.1848 Blender version: 3.5 LuxCore version: 2.61

PC Specs: GPU: GTX 1650 for laptops (4GB VRAM) (Selected to be rendered with) CPU: AMD Ryzen 7 3750H for laptops RAM: 16GB

Are you tried also update graphics driver to latest one?

I just updated my graphics driver and restarted my pc. It still doesn't work and the error is the same.

Same issue here on latest windows 11 update. Intel ARC drivers are up to date. Windows 11 build 22621.

I updated the first comment so that it has my PC's specifications at the end. I use the GPU for (attempting) rendering.
