Proximity sensor not coming back after killing all sensors with HKS
While on a call I just noticed that the display would not be blanking (and my cheek started wildly generating touch inputs), so I checked with monitor-sensor and it told me === No proximity sensor.
On a fresh boot the proximity sensor is there and working fine.
If I then engage all killswitches all sensors (accelerometer, ALS and proximity) are still being shown with the sensor readings frozen to what they last reported:

This is lsmod (hope it's relevant?) with with all HKS engaged:
I'm not sure which modules I'd expect to show up here,
st_lsm6d (for gyro/accelerometer/etc right?) was the only thing I could somewhat identify
