FanControl crashes during PawnIO driver install after clean reinstall (Win11 24H2 build 26100.6725)

[serveradmin9912]

Describe the bug
FanControl worked fine until today (Oct 14, 2025). Suddenly stopped detecting all sensors during normal use.
After full reinstall, it now crashes when PawnIO tries to install its driver.
Happens every time during setup, regardless of Safe Boot or unsigned driver mode.

Steps taken

• Uninstalled FanControl and PawnIO completely
• Deleted all leftover folders
• Updated Windows 11 to current version: Windows 11 Pro 24H2 (KB5065789) build 26100.6725
• Disabled Windows Defender Threat Protection
• Installed FanControl_244_net_8_0_Installer.exe
• Accepted PawnIO install prompt → crash (see screenshot)
• Repeated 5x with Safe Boot on/off and Test Signing enabled/disabled → same result

Do you have Face IT AntiCheat installed ?
See: namazso/PawnIO.Setup#1

Seems like the FaceIT issue.

Seems like the FaceIT issue.

Yes, I have Faceit AC installed and I’ve heard about that issue.
Strangely, it worked fine for me until yesterday, and I’ve been playing Faceit CS:GO almost every day, so I assumed I wasn’t affected.
