I re-installed this driver now on my rig. I can confirm the issue.
Same message in GpuCapsViewer and no OpenCL GPU found in Blender.
I guess NVIDIA started OpenCL 3.0 development and put some broken code in this driver branch 💩
If you can live without the WSL feature i suggest to try driver 456.38
So what does advanced tab in GPU-Z read?
In which application did you notice the issue?
Check OpenCL in GPU Caps Viewer.
Last time i had such an issue i installed the same driver on top of itself for complete installation.
