FanControl shows error (System.ObjectDisposedException)

[E14]

Describe the bug

FanControl shows generic error message.

This may be connected to sleep/hibernate but I'm not completely certain, please tell me if you need additional information.

Is there a log.txt file next to FanControl.exe with recent date entries?

Is it a one time thing or it happened multiple times?

[E14]

This happened multiple times, but not regularly log.txt

Hi Rem0o, I have the same exception too, it appears after waking the PC from sleep. My configuration is:

• R9 7900
• MSI MPG B650I EDGE WIFI
• 7900GRE

[RheologyOrbit]

I'm also experiencing this issue. I get this error every time I resume from sleep.

Specs:

i7-12700k Radeon 6950xt log.txt

FWIW, it doesn't seem to actually affect anything for me, it's just an annoying popup.
