That sounds like a connection problem. Make sure you are using a good new cable too and that it is properly seated. If this is happening with every flight it is likely a hardware issue.
Your most recent flight log has this entry:
dji_check_center_Gimbal_disconnected / dji_check_center_rc_disconnected / dji_check_product_disconnect_reason / dji_check_center_Camera_disconnected / dji_check_center_mc_connection_reason
That is generally the sign of something going on with the aircraft. It is basically saying everything is broken.
Please check for normal operation while using the DJI app to make sure everything is healthy.
Also make sure all other drone related apps are fully closed.
You can always use the RTH button the remote if something goes wrong during flight.
