i have a prospector dongle that no longer reports battery from my halves. It stopped after I added cmake-args for brightness and removal of light sensor (and now later some more args to attempt to fix it)

cmake-args: -DCONFIG_ZMK_SPLIT=y -DCONFIG_ZMK_SPLIT_ROLE_CENTRAL=y -DCONFIG_PROSPECTOR_USE_AMBIENT_LIGHT_SENSOR=n -DCONFIG_PROSPECTOR_FIXED_BRIGHTNESS=80 -DCONFIG_ZMK_STUDIO=y -DCONFIG_ZMK_SPLIT_BLE_CENTRAL_BATTERY_LEVEL_PROXY=y -DCONFIG_ZMK_SPLIT_BLE_CENTRAL_BATTERY_LEVEL_FETCHING=y```
It has worked before without problem.

Are you paired to the dongle over BLE?

Your configuration looks fine to me, so I am not sure what can be the cause from the keyboard side
