Conbee III unresponsive and not flashable

Hi,

since yesterday I’m facing a big problem with my Conbee III. After updating my docker from 2.31.2 to 2.32.5 the conbee III became completely unresponsive after the docker booted. No connection to any device.
So I downgrade to 2.31.2 again but the stick also did not responde.
I replugged it several times and also tried to flash the newest firmware again. The stick and the port is recognized but the firmware update fails everytime. I used GCFFlasher_Win_V4_09_00

GCFFlasher Error

Did anyone had the same Problems before and can give me an advice to fix this?
I tried my backup solution Conbee II i had laying around and after changing the usb path in my docker settings everything was back up.

Hello, can you make the try on a real hardware ? (not a docker)

i tried to flash it on windows 11 with my computer. the docker running on unraid in my homeserver.
