Lost CPU sensor monitor on v277 for Gigabye 870E Aorus Extreme

Since updating from v276 to v277, I've lost my CPU sensor, and now all fans are misbehaving because that monitor is tied to CPU TCTL/TIDE. Force apply doesn't work. The "?" over the CPU sensor is persistent.

I tried a complete reinstallation, removing all previously installed files. I've also updated PawnIO to the latest version (2.1.0.0. -> 2.2.0.0).

I've tried manual calibration; it seems FAN Control has lost access to the CPU sensor.

I checked AID64 and the sensors are being picked up just fine.
