EyeTracking calibration no longer works

[DrAdamStreck]

Once we start the calibration process from Unity, using the

SRanipal_Eye_API.LaunchEyeCalibration(IntPtr.Zero);

the environment changes to the grey calibration screen and displays "Loading" with the loading animation. This disappears after about 5 seconds, and only the gray background remains. Previously, we would see an animation that would advise us on correct positioning of the headset. 

If we try to restart our application once the calibration has been started, our application freezes.

This issue has appeared last week and it seems it follows after the SRanipal SW auto-updated. We have reproduced it on two different PCs.

Hi @DrAdamStreck,

Could you provide us the log for further analysis?

Find the SR_runtime from Windows System Tray and right click the icon to select "pack log".

Thanks.
