Not possible to enable flashlight when Tango service is running

[lvonasek]

When I enable flashlight before starting Tango service then starting Tango service turns flashlight off.
When I start Tango service then there is no possibility to start flashlight.

Is there some reason for it? Here is scan of a cave using external flashlight: https://skfb.ly/6rBZn (drifting correction worked, texturing worked, scanning worked).
