Interesting, Virtual Desktop library (thanks to microsoft) tends to break quite often but I haven't seen this specific issue yet.
Did you also update windows by any chance?

[madface303]

Last Update of Windows was on 14.1.26, i think i installed version 2.2.0 a few days later. After update of windows it worked, as i use this sensor quite everyday (its used cycling the desktops with a zigbee button using homeassistant) and so i notice it very soon.
Does the sensor work for you as expected, so it is my windows installation?

[amadeo-alex]

I'm not so quick to make definitive statements.
I'd prefer to assume something is at HASS.Agent's fault first and then deduce otherwise than the other way around :D

Could you please enable debug logging in the settings, close HASS.Agent, start it up again and provide the logs? (and redact any names/hostnames/IP you wish)

Sorry for the delay, i missed the last sentence of your answer. Here ist the log with extended logging enabled:

That is strange, the library initialises but then throws errors.
Looks like I'll need to try and replicate it, because I have no idea why it has an issue. You upgraded to 2.2.0 directly from 2.1.X?
What is your full windows version? (the numbers)

[madface303]

Yes, i think it was the 2.1.1 (i did not use one of the betas in the meantime) and i did a direct upgrade as HASS.Agent told me there is a new version.
My OS Build is the 26200.7623.

Thanks for caring!

I also can confirm that all previous versions prior 2.2.0-beta1 with .net6 ( with virtual desktop IDs are working with Windows 11 (all builds (LTSC)
