[Windows] SIGTERM / Crash on connection

[rokk4]

Using the example app results in a crash when connecting.

The issue was always there, in all LiveKit versions that I tried, not just the recent releases.

The WebRTC Example App is working fine for me on windows.
How can I try to debug this?

hey @rokk4, thanks for reporting this. We are still working on Windows so there's likely a few issues with it. We are making a note of this report and will investigate.

[cloudwebrtc]

@rokk4 I will try to investigate this issue,

[rokk4]

@cloudwebrtc Thanks for your efforts, please let me know if I can do something to assist.

After fixing a few bugs, it works fine on flutter 3.0.1, I need to fix the upstream native sdk, which should make the windows version stable soon
