Connect IQ Device Simulator - not working (empty window)

Hi,
I'm unable to successfully launch the Connect IQ Device Simulator.

Whether I launch it from the Eclipse (menu Connect IQ->Start Simulator or by Run As -> Connect IQ App) or directly from SDK dir (simulator.exe) I always end up with the same result - an empty window:

And when trying to connect from Eclipse:

Some specs:

  • System: Windows 10 (64)
  • SDK Version: Connect IQ 3.2.3 (newest for today)
  • Devices: all available ;)
  • Eclipse: 2020-09 (4.17.0)
  • Connect IQ Device Simulator: 3.2.3

What I've tried so far:

  • Restarting Windows ;)
  • Reinstalling SDK
  • Installing different version od SDK (and of course switching to it)
    • From 3.1.8 to 3.2.2, the interesting fact is that since version 3.2.1, the SDK is way smaller,
  • Installing Visual C++ Redistributable Packages
  • Playing with PATH and SDKROOT environment variables

Everytime the same result :(

Any ideas what else can I try? Maybe some of you have encountered a similar problem? Is there any place I can find the Simulator logs?

Thanks in advance :)
