I'm gonna guess you removed the battery and reinstalled or tried another battery?

I never liked the way the batteries "soft click" into place, vs top loading batteries or the Evo 2 Pro. I usually give them a solid shove with the base of my hand or hold them 3/4 of the way out holding the drone camera down and let them gravity drop into place. Then I get a solid click of the spring locks. Perhaps you could try for something similar

I am not really sure what happened. Drone just displays that message now.

Did you try another battery?

I gave it a thorough session of battery attempts. At one point the alarm delayed for about ... 5 seconds. Then re appeared. I think once that switch is tripped, the quads disabled, tbh. Its a relay, with a connection, and the switch, and I think inside it, its "broken". The switch is the most tiny thing I ever seen too, take a look inside the batter compartment with an eye piece. They are under the metal sensor.

Seems to be a delicate thing inside the drone (the sensor you describe).
Would rather turn it in for guarante repair, still to new for trying anything else.
