unable to connect to Windows 10 since krdc 24.02

As of the plasma 6 upgrade and krdc 24.02 I'm having trouble to connect to my Windows 10 Notebook with krdc.

With QT-Logging set to info, I can see the following output

QT_LOGGING_RULES="com.freerdp.info=true" krdc

When connecting with the wlfreerdp command line no such issue occurs.
