Can't download logs via MavLink - 0 bytes

ArduCopter Copter 4.5
1

I do “first flight” on SpeedyBee f405 mini. And want to analyze logs.

Arducopter 4.5.7 (the same on 4.6.0-beta)
MissionPlanner 1.3.82 build 1.3.8979 (the same on beta 1.3.9151)

LOG_BACKEND_TYPE=block (internal flash).

I can see that log exists (3,7Mb):

But on downloading I get 0 size file.

Logs from the Mission planner ConsoleL:
