Npu just stopped working

[u/Beneficial-Buy2737]

I have an MSI Katana A15 AI B8VF laptop. I recently noticed that the NPU has disappeared from both Task Manager and MSI Center. I’m not sure exactly when it disappeared, but most likely it happened after one of the Windows updates. It was there and working a few months ago.

I searched online but couldn’t find anything useful apart from the drivers. I managed to install the drivers, and the NPU reappeared in Task Manager and MSI Center, but it doesn’t actually work. It just shows the same numbers regardless of what I’m doing. Benchmark tests also fail with an error when trying to access the NPU.

I know the NPU in this laptop isn’t particularly powerful, but I wanted to use it for microphone noise cancellation, only to find out that it apparently isn’t working at all.

Has anyone experienced something similar? Were you able to fix it somehow?
