System.Exception: HWInfo sensors failed

[FlemmingJPetersen]

Sometime FanControl stops reading sensor info, and here is what is in the log:

2023-06-22 15.21.12: HWInfo sensor failed momentarily during operation: HWInfo/ASUS TUF GAMING Z690-PLUS D4 (Nuvoton NCT6798D)/CPU/RPM - Missing

Somethimes the error is slightly different, but the result is the same:

2023-06-19 07.47.09: Unhandled exception in FanControl v160.0.0.0

I'm seeing the same error:

HWInfo Version 7.60-5170

Any update or progress on this issue?
I'm getting this error almost hourly.

So I have kind of fixed the problem by disabling the CPU current draw measurement in the HWInfo app itself:
29/07/2023 11:30:03 am: HWInfo sensor failed momentarily during operation: HWInfo/ASUS EC: ASUS /CPU Core Current/A - Missing

Seems the fan control plugin has issues if one of the HWInfo sensors goes missing.
