Lost connection

[rddl]

Hello,

Today, I did some tests with my Air3 /RC2.
Takeoff : 2 meters - distance 2 meters.
Rc2 and Drone lost connection after changing video to pano mode.
I restarted the RC2, but it could not connect to the Air3.
I wanted to catch the drone by hand with thick gloves, but it lifted.
I wanted to move it with a top umbrella : Air3 did not move
I was waiting for a power loss, ready to catch it, but heard a Rc2 connection, and drone landed alone.

The place I use is safe, I did use it with a PV2+, a Mavic Air, An Air2, without such problem.

I replaced the battery, did some tests at same place / altitude without problems.
What might have happened ?
I will copy flight logs in my computer using DJI Assistant 2 to see if I can understand something.

Unable to view my logs :
Flightreader says there is a problem with my logs
Online reader says I need txt files,

DJIAssistant 2 exports log files. Or, dat files.
Dat files are huge : > 1.5 Go

I got help from Mike (Flight Reader)
Using a Rc2,
txt log files are in Android --> data --> dji.go.v5 --> files --> FlightRecord

log stops after message stating "connection lost"
