Yakut slcan not working

Hello. I have a problem with yakut on Windows 10:

set UAVCAN__CAN__IFACE='slcan:COM2'
set UAVCAN__NODE__ID=10
yakut monitor

After selecting slcan protocol and run, I have a problem on yakut side:

InvalidMediaConfigurationError: Interface not supported yet: 'slcan

yakut version is 0.11.1

This should not be possible:

Please re-run with -vv.
